Someone with a decent longpost analysis blog on tumblr mentioned it seems like the kids went on some camp trip in the summer (the point where Kel and Sunny go bug hunting and Hero gets frightened by a stag beetle), and it may have been memories of the camp showing in Headspace as wandering the bug-filled Pyrefly Forest after the Prologue as well as the log rafts in Humphrey and the forest in Black Space. So they figured that Long Legs is a subconscious thing based on memories of a camp counselor, who represents adult guidance and responsibility, and the role of bringing festivities to a close.
