Treehole

Treehole is the slash ship between Tree and Black Hole from the Battle for Dream Island fandom.

Battle for BFDI
Tree tells Black Hole to do 'the thing", which is sucking up the top halves of the jawbreakers.

Tree asks Black Hole if he can spin their swing, but Black Hole says that he can't push anything, but he can pull like there's no tomorrow. Remote says he's wrong as there is a tomorrow, to which Black Hole replies that he can literally slow down time so that there is no tomorrow. Tree says not to do that and to just do their 'pully-attracty' stuff.

Tree gets mad at Pen for trying to use Black Hole to win the challenge. Tree reads a book on what to do if you have a problem, which said to ask Black Hole. Tree asks Black Hole if he can draw, and Black Hole says he can't, but can form an accretion disk.

When Tree, Bottle, Pillow and Pen are blocking the forks, Tree says that Black Hole can suck them up.

When Black Hole says "And that's how you prevent death! Simple as that.", Tree is reminded to recover Pie for the challenge.

Black Hole tells his team he's disappointed in all of them, including Tree, for going to the spikes of the Evil Canyon, where they could easily die, along with how none of them seemed to care that Pillow 'died'.

Tree says that if Pillow was killed, they should go recover her, and Black Hole agrees.

Tree asks Black Hole if he thinks they're wasting their time as they could be leaving already, and Black Hole says they can just take their time while pointing out how happy Remote is, which annoys Tree, because he said he would rather be in the sun than in The Fourest.

The Power of Two
When Tree says that they just took Pen into their team, Black Hole says that he remembers that.

Tree looks at Black Hole angerly when he sucks up all their blocks.

After Pen stops Black Hole from sucking up his team's blocks, the first thing Black Hole wants to do is tell them about what happened, but Tree interrupts saying that Teardrop ruined their stack.

After Teardrop killed almost everyone on Death P.A.C.T. Again and Black Hole accidentally killed Teardrop, Black Hole frantically tells Tree that they need to recover everyone. Tree tries to ask what happened, but Black Hole just said there was no time. Tree shrugged and went to go recover everyone with Black Hole.

When Black Hole said they'd hoped Pillow would stop killing, Tree questions how he kept the optimism the whole time, which indicates that he lost hope that Pillow would stop.

Tree tells his team that they should steal more blocks, and Black Hole asks why. Tree replies saying they don't have very many, and Black Hole says they have enough, they don't need to be the taller, they just need to make sure they aren't the shortest. Tree tells him that's an efficient way of looking at it, and Black Hole says it's the normal way of looking at it, because it's a fact, to which Tree gives a slightly annoyed look.

Due to all the deaths caused by Two's blocks, Tree said they might forfeit the challenge on purpose to focus on preventing death, and Black Hole and Marker agree.

When Tree was bouncing on the landing pad they made, Black Hole tells him to stop and that he's treating it like some sort of amusement park attraction.

When Marker faints onto the landing pad, Tree turns to Black Hole and says that they'll consider that as Marker's save a death prevention.
