Eons before the events of the series, the lava lamp shaped creature committed crimes before being called together by Bill Cipher, along with 8 Ball, Amorphous Shape, Hectorgon, Keyhole, Kryptos, Paci-Fire, Pyronica, Teeth, and Xanthar.

Season 2
The lava lamp shaped creature is first seen in "Weirdmageddon Part 1". The being is among Bill's friends when he is introducing Ford to them. Then, it leaves for the Fearamid with most of the gang. Later in the episode, it is seen partying and playing "Spin the person" and enjoying the "V.I.P." party Bill is having at the Fearamid until Time Baby and the Time Paradox Avoidance Enforcement Squadron interrupt their party.

In "Weirdmageddon 2: Escape From Reality", it is seen again dancing in the Fearamid, before Bill announces they're taking chaos worldwide.

In "Weirdmageddon 3: Take Back The Falls", it's sucked back by the portal along with the rest of the creatures from the Nightmare Realm.
