Season 2
WHATEVER HAPPENED TO DELLA DUCK?!

As Della is about to be attacked by a moon might, it is suddenly hit with a laser and burrows beneath the surface. Della looks to see an alien woman holding a phaser and tells her to halt. Della is extremely confused and shocked when the mite comes up and starts to steal her ship. Della runs to the ship as the woman tells her to not ignore her. The ship disappears below the surface and Della starts to dig, and the woman demands to know who she is and how she got there. Della introduces herself, says that she has a millions questions, but has to get her ship to get home first. The woman is about to shoot, when a man tells her, Lieutenant Penumbra, to stand down. The man introduces himself as Lunaris and welcomes her to the planet moon. Della says that the moon isn't a planet, and Penumbra tells her to treat the moon with respect or suffer the consequences. Della says she will, after she finds the mite, but Penumbra says that they've been hunting them for longer. She doesn't expect and earther to find it, when the ground beneath them suddenly gives out and sucks them to the caverns below.

A moon might then appears and Penumbra and Lunaris start to attack it. Penumbra suggests feeding Della to it to distract it, but Della says that they know this whole adventure is gonna end with them becoming best friends. So, suggests Penny moves it along. Penny says that her name is Penumbra and starts to charge at the beast as the other two follow. They figure out what the Mite wants and Della gives it the last of her gold to feed its baby. She asks for Penny and Lunaris' guns, and Penny assumes that she's going to attack the Mite now that it's vulnerable. They might become best friends, but she is quickly disappointed when Della just gives them to the mite's for food.

The two take her back to their city that is almost entirely made of gold. Della can't believe she was in the desert this whole time while this was around the corner, and Penny points out that that's why she called her a dummy. Della can't believe the amount of gold, and both Penny and Lunaris say that almost everything there is made of it. Della thinks that infuriating and amazing and hugs Penny, since she can now fix her ship. Penny struggles out of the hug, and Della decides that they're officially best friends. As she runs off, Penny can't believe that Lunaris is letting her stay there, but Lunaris suggests that she should be useful. Penny thinks dangerous is the more likely answer, and Della better watch her back.

THE GOLDEN SPEAR

As Lunaris takes Della back to the city, Della sees the statue of him and Penny. Lunaris explains that Penny is considered a hero on planet moon, but Della corrects him on the moon being a planet. Penny then springs forward, yelling that the moon is a planet and holds Della upside down. Della cheerfully says hi to Penny, and Penny yells back that her name is Penumbra. Della asks if it's moon custom to yell, and yells back her hi. Lunaris says that Penny is now a warrior with no war, since the mites are now gone. Della sees this as an extended vacation, and asks what Penny is going to do now. Penny drops her and says she's going to seethe. Della unconvincingly says that sounds fun, but needs to get back to working on her ship. She heads off and Penny says that she's not suspicious, before telling Lunaris that she believes that Della is lying. Lunaris doesn't think so, and sees Della sleeping on the ground. He then tells Penny that Della will be staying with her, under orders.

Penny is looking up at her statue when Della ends up startling her. She fires her blaster, but Della ducks out of the way and to be careful of burning down the garage. She mentions that Lunaris told her that Penny had volunteered to let Della stay with her, and Della couldn't say no to her best friend. Penny enters the house, and Della calls them a classic odd couple. Penny has no idea what that is and Della thanks her for letting her stay. She picks up a spear, and Penny grabs is from her. Della is reminded of her own Spear, the Spear of Selene, and needs to get back to work on hers. She realizes that they both have "spears", and calls it neat. Penny insists that it isn't but Della just leaves as she insists that it is.

Penny becomes annoyed with Della's stories of earth that she tells the other moonlanders, and decides to play the game. Della is happy to see her come over and floats down to hug her, hoping that a shenanigan will happen at some point. Penny says yes, and it's one of the reasons that the moon is better than earth. Della says that they can both be great, and Penny fires at her, only to miss and hit her house.

Penny wakes to the sound of Della's rocket starting and goes out to see what's going on. Della announces that the rocket is fixed, and the moonlanders chear for her. Penny yells that if they think it's so great, why don't they all go back to earth with her. The moonlanders think it's a great idea, but Della says that the ship is to small to take everyone, disappointing them. Penny gets an idea, and insists that Della could do it if she really wanted to. Penny says that nothing could stop Della, and calls her a failure and a liar, when Della gets an idea. Penny says no, but Della says that Penny is right and will find a way to get them to earth.

Penny is insisting to Lunaris that Della is lying about everything, when Della appears and asks who they're talking about. Penny plays it off that it wasn't about her, when Della pulls out Penny's spear, now fixed instead of broken. She hands it to Penny, since they helped fix her ship, it's only right that she fix something of hers. Lunaris thanks Della for Penny, and Della pulls out a picture of her kids. She says that because of them she has a chance to be a mom again, and knows what it's like to trust her people with someone else. As long as the moonlanders are with her, she'll try as hard as she can.

Penny decides that Della isn't pure evil, but doesn't want her to take the moonlanders with her to earth, and questions why she can't go now. She then gets an idea, and takes a sleeping Della to the top of the rocket. Penny then starts the rocket and wakes Della. Della realizes that the spear is taking off and asks what happened. Penny lies that there was a malfunction, and Della can't reverse it. Penny insists that she go back to her family, but Della already promised to take the others with her. Lunaris appears and says that they'll build new ships with her plans, and she hands them over. She quickly gives Penny a goodbye hug before jumping into the ship and leaving.

THE RICHEST DUCK IN THE WORLD

Dewey sets up his Dewey Dew-Night segment, and starts to interview Della. Della asks if they can send her message now, and Dewey gives her the floor. Della says hi to Penny, but Dewey interrupts to ask who Penny is. Della explains that she's her best friend and Dewey asks how they met. Della explains that her ending the war with the mites took away Penny's whole reason for existing and Dewey assumes that it must have made her mad. Della doesn't think so, but does remember how the moonlanders started worshipping Della and ignoring Penny. She did also try to playfully kill her a few times. Dewey suggests that Penny helped her get home to get rid of her, and Della stats to think that might explain a lot. Why she hasn't called, and that maybe they were never friends. Della then becomes sad and leaves.

Della is in the houseboat, cleaning up the recording equipment when Dewey joins her. He apologizes for everything and assures her that Penny is probably just caught up with moon stuff. Della says it's fine, and that you don't need moon friends when you have your family. She starts to unplug the radio, when a message from Penny comes in asking for her. She then warns her that Lunaris and the moonlanders are invading earth!

MOONVASION

The Duck family is seemingly at an end when Penny crashes her ship and destroys Lunaris'. She then lands on the Duck's ship and says hi to Della. Della is excited to see her, and starts introducing her to her family. Penny tells her to let her in, and Della realizes that she should probably do that.

Season 3
THEY PUT A MOONLANDER ON EARTH!

Della enters the plane hanger, and finds Penny working on her rocket. She climbs up to meet her and calls, causing Penny to hit her head on the rocket in surprise. She says hi back, and continues to work on the rocket. Della thinks about how it was similar on the moon, but this time Penny is the one building the rocket at her house. She asks if she needs help, and Penny hands her a tool and thanks her for the offer. Della says that Penny doesn't have to leave earth, and that she hasn't experienced anything yet. Penny corrects her, since she went out for coffee. Della assumes it was a date, and Penny tells her that she went with Launchpad, confusing Della. It went badly, and Penny just sees it as another reason she should focus on the ship instead of exploring the planet. Della half jokes that she's more scared of trying new things, but Penny insists that she's not, before coming to the conclusion that Della must be joking. They're interrupted by Dewey and Webby asking to go to the pier, and Della suggests they take Penny with them. Webby is excited, but Penny says she can't, since she has a meeting with the other Lunarians.

Quotes
"Oh, good plan. Lull the beast into a false sense of security only to betray them when they're at their most vulnerable. Heh, maybe we are becoming best friends. Della gives the guns to the mother mite. [Della gives guns to mite's] Boo! You disappoint me in every way possible."

- Penumbra; What Ever Happened to Della Duck

Fanon
The ship is well like by the DuckTales fandom. Mostly relegated to art and moments drawn into comics. While fic is still a part of the ship it is less so than in other DuckTales ships. This is most likely due to Penny's limited appearances and the 2017 reboot being the first appearance for both characters, so there are no subsequent pieces of media to help support the ship. The ship gained a more pronounced following "They Put a Moonlander on the Earth!" when it was hinted that Penny was a lesbian, and later got confirmed on twitter. It gave many Dellumbra fans hope that it would be canon someday, even if not right away.

Dellumbra is the most popular femslash ship in the Disney Ducktales fandom, much like how Cassunzel is considered the main femslash ship in the Tangled fandom. compare the Ducktales ship with the main Ben 10: Omniverse ship, Benrook.

Fans of the ship often depict Della helping Penny get used to earth culture. The height difference between the two is also depicted in most art. Either having Della standing on objects to be on equal height with Penny, or just having Penny pick up Della. Another common depiction is Della's kids, and Webby, reacting to their relationship. Many believe that Dewey would be the happiest at the idea of having two moms.

Delpad is often considered a rival ship for Dellumbra, but fans don't engage in ship wars for the two. Most can acknowledge the good stuff in each ship while having their own preferences.

On AO3, Dellumbra is the most written relationship for Penumbra and the third most written for Della.
