Fantube

Fantube is a het ship between Fan and Test Tube from the Inanimate Insanity fandom.

Canon
Test Tube and Fan are both contestants in Season 2 and 3. They barely interacted with each-other until Let 'Er R.I.P, when they found out they have a-lot in common. After that challenge, they interacted in a-lot more scenes.

Let 'Er R.I.P.
Test Tube tells Fan about the waning crescent, and Fan expresses how commodious it's, but small at an angle, and how it relates to him like the show. The two sit down as Fan confesses that he was superabundantly awkward, and Test Tube relates to him. When MePhone5S and Mephone5c were targeting Fan and Test Tube, Fan tricks them into jumping off the 60 Foot Cliff and promptly causing their death.

Everything's A-OJ
Fan starts writing a blog post on Lightbulb's shattering and asks Test Tube inquiries how long it will take for her to shatter again. During the song, Test Tube researched Fan's Egg as Fan writes on his computer. Later on, when Paintbrush accidentally drops Fan's egg, Test Tube comes to its rescue, to Fan's sweet relief, saying he is extremely grateful.

Theft and Battery
Both are ecstatic about going to MeCloud. When Steve Cobs tries to take Fan's egg away, Test Tube is the first to step in. They don't interact much until their balloon falls to the ground (courtesy of Toilet), and they both hold each other close when falling. Once they're about to die, they grasp their hands.

Mazed and Confused
Fan asks Test Tube to hold his egg for him while he does the maze with Lightbulb, making sure Lightbulb does not break it. During the maze contest, Test Tube is here trying her best to protect the egg while she's burning. Fan asks if she's okay after the challenge. At the end of the episode where Spoiled Lemon is playing, Fan is holding a burned Test Tube while watching the band.

Kick the Bucket (Part 2)
Fan was trying to help Test Tube to throw the ball. She was thrown by Lightbulb into the lake. She did not understand what Fan meant. However, she successfully threw the ball, and the Bright Lights won.

Alternate Reality Show
Fan was desperately concerned when he found out Test Tube was missing. Later in the episode, Fan and Test Tube were sitting on top of the vending machine blathering about Test Tube's time-traveling adventure. Fan is upset they can't use it again because it could help create thematic parallels.

Hatching the Plan
Test Tube is the acknowledged contestant that's affected by Fan's abduction the most. Test Tube later apologizes for getting upset at him in Mine Your Own Business and hoping things will be different.

The Shame of the Name
Test Tube tries to talk Fan out of confronting Cabby. So he does not get eliminated. Test Tube is the only contestant on The Pinkers to persuade them into not voting for Fan at the elimination. When Fan was getting eliminated, she made a promise that she would Bow when the time was right.

Fanon
FanTube is the most popular ship in the Inanimate Insanity fandom. This ship has a big fanbase with millions of fan art. It became popular ever since Let 'Er R.I.P.
