Bruno was once trying to catch fish when he fell into the arctic ice flow. Sealed in a block of ice, he became the main attraction of the Kushman Brothers' carnival.
As time passed, Trixie the Giraffe-Necked Girl fell in love with him, and convinced local fire breather Flambé to set him free, after which the couple ran off together. They managed to travel and meet other bigfoots around the country before the two of them got captured by Conroy Bumpus and taken to Bumpusville as a supporting band. Luckily, Sam & Max find and set them free shortly afterwards. However, Bruno and Trixie run away again, not wanting to return to being a part of the carnival's freak show. Bruno is later found in the Savage Jungle Inn, attending an all bigfoot party with his plus one, Trixie. For the rest of the game, Bruno stands near the totem poles and attempts to "help" Sam and Max by interpreting them.
