Fluffles is a cat owned by Runt. Max made fun of Runt about it due to his mother forcing him to bring it to school due to her paranoia about creepers attacking Runt. Runt also accidently used Fluffles as a piece of wool when he was trying to raise his crafting score. Fluffles's favorite food is pufferfish.
Role in Project X
After Max made fun about it, Runt wanted to make his team name "Danger Kitty" for the big building test to try and get back at Max for making fun of him. The name was inspired by Max calling Fluffles "Danger Kitty."
Runt and Stump won the building test and left Max shocked.
