You walk up behind the bathrooms in The Plains to see Bottle with Tree stuck inside her and Black Hole trying to suck him out.

Black Hole:Ugh. Won't budge. If I go any further, I'll be causing both your deaths, so no good.

Bottle:Heehee! Tree keeps moving around in me!

Tree:How did I even get in here!?

Bottle:I have no clue, hehe!

Black Hole:How do you not get mad at her?

Tree:I'd sure like to know...
