On the meteor, Rose, Dave, Kanaya, Terezi, and Karkat find themselves passing through a series of hooked-together dreambubbles inhabited by some utterly inexplicable grubs. Grubs that squeak and fuss and cling and chew holes in their clothes. Grubs who resemble to a distressing extent trolls whom the meteor-dwellers killed or were killed by, but essentially grubs who need someone to see to them, even in dreambubbles out of time.
