Mr. Tentacles was a squid character associated with MarioMario54321's Roblox videos. Most of the time, he rests on MM's head. His appearance is a squid with the color of gold. He is named after the tentacles of cephalopods, such as himself. He now hates MM54321 due to him being abandoned for the Golden Fleece item. He also encourages people to buy Splatoon.
