Rubook

Rubook is the femslash ship between Ruby and Book from the Battle for Dream Island fandom.

Canon
While the FreeSmart Van passes through a snowy biome, Ruby grabs a clump of snow and throws a snowball at Book. As the two engage in a snowball fight, Pencil warns them not to do so at the risk of snow mixing with gasoline.

After Pencil asks Ruby if she went to gem school, Book tells her that gem school is for diamonds only. Book suggests that Ruby pushes Evil Leafy's purple button after Pencil is vaporized away. The button transforms them into regular size and teleports them right by Evil Leafy. The two try to quietly walk away but must quickly evacuate after Evil Leafy spots them. After being chased for a while, they climb up a tree and Ruby instructs Book to cut a rope with a weight on the other side. They high-five after the weight crushes Evil Leafy, Fries, and Puffball. Book, however, realizes that they can't recover their dead teammembers because of the recovery center being inside Evil Leafy, saddening Ruby. On-screen text indicates that Ruby "died from sadness" and Book used her remains to make billions of dollars. The two, however, make it back with the four other alive contestants and must crank a machine with them to produce a new recovery center.

Ruby tells Book that she didn't actually die from sadness after Book questions it. Match invites Book and Ruby to have a break from cranking with her. While Match decides to stop cranking the rest of the time through, Book and Ruby return to the machine once her timer goes off. After they finish cranking, Book tries to calm Ruby's fears of the machine exploding. She states that it self-destructing could potentially mean it disappears without a trace. As the machine's counter hits zero, Book stops Ruby from hallucinating its explosion and proves that it simply vanished. The two help with recovering the rest of their team and head out to complete their journey to Yoyle Mountain. Book and Ruby later engage in another snowball fight as they drive past the desert. Throughout their drive underwater, Book recovers Ruby among other team members when she loses her breath.

Book warns Bubble and Ruby that they will turn into metal after eating yoyle-berries. Ruby does not listen and turns metal accordingly. When Ruby asks how they're going to free Pencil from the fish monster's grip, Book suggests killing her and recovering her with the Hand-Powered Recovery Center.

While falling from Yoyle Mountain's summit, Ruby asks Book if she would like some yoyleberries. Book, although suggesting she would've rejected them in an alternate universe, accepts and eats them. For the challenge, Book and Ruby hop in the FreeSmart Super Van as Pencil drives them around the city looking for a place to sleep. Book is excited to visit the Pillow Marketplace when Ruby suggests going there. After a few hours of driving, Ruby opens Book's pages to find where the Pillow Marketplace is. She learns that the mall is a part of a larger building in which the stairs for them are broken. Book suggests getting balloons so the van can float to the 276th floor of the Yoyle Needy, where the marketplace is. After having brought balloons from a store, Ruby and Book comment on the historic buildings they're flying over. They later come across a pipe and are about to fly right into it. Since they are in the air, Pencil can not drive around it and they end up crashing into it. The three must hold their breath as water starts flowing into the van. Before they drown, Book suggests that they grab snorkels and puncture holes of the roof with them to breathe. Book is scared that they will lose the challenge and Ruby is sad that they won't be able to visit the pillow marketplace. The team ends up in conflict with W.O.A.H. Bunch and after brawling, Book and Ruby come to a realization that they're forgetting to sleep for the challenge. Ruby hands blankets and pillows to her team as they try to sleep away. To avoid further confrentation with Evil Leafy, Ice Cube attaches balloons to her team so they can sleep in the air. After the challenge, Book supports Ruby's idea on starting a video diary for the team and grabs a camera for them to use. Ruby snatches the camera from Book to her annoyance.

During day 20 of their video diary, Book records an aurora borealis and captures Ruby catching a shooting star. The team later overhears the challenge wheel being spun and as each member works to pop each other's balloons, Book is biting away at Ruby's balloon. Ruby wakes Book up after falling and alerts them of intruders on their team. Book learns it's Firey and Gelatin and comments her stances on the two. Since they didn't land in time to know the challenge, Book, Pencil, Ruby, and Ice Cube must listen to Firey and Gelatin on the challenges they tell them to do such as doing jumping jacks, smashing windows, and traveling through planets. As Firey jokes that the contest is to actually kill their teammates, Ruby rips Book in half. She later recovers the team and explains to Book why she killed her.

Book informs Ruby that since she didn't know what a lens cap was, there is a chance every single video diary they recorded was obstructed by it. Later when Pencil is falling from the top of Yoyle Needy, Book instructs her and Ice Cube to run down to catch her in time. She warns Ruby not to jump down the center of the staircase, but she does so anyways and shatters. After catching Pencil, Book reminds her to recover Ruby along with Bubble and Ice Cube. Book walks to the Hand-Powered Recovery Center and dances with the team after recovering Ruby. Later during the credits, Book and Ruby encourage viewers to recommend characters for the new season.

Fanon
Rubook has decent support in the fandom, although not necessairly to a great extent. Rubook has been referred to as a rarepair by the community but, however, has a following in terms of fanart. Fans who support the ship enjoy their bond throughout being in Pencil's alliance in the second and third season. Dozens of art of the two can be found throughout DeviantArt along further support on platforms such as Tumblr and TikTok. Rival ships between the two include Floweruby (Flower x Ruby), Booklow (Book x Pillow), and Tacobook (Taco x Book).

The ship currently has one written work on AO3.
