This papercraft is the Marvin the Mouse, based on the game Conker's Bad Fur Day, the paper modelwas created by Paperlegend. Marvin the Mouse is a mouse critter that appears in Conker's Bad Fur Day and Conker: Live & Reloaded who has a habit of burping and farting from time to time in which his gases cause Conker to vomit if close to them. When first entering the Barn Boys area, Jack the talking metal block asks Conker to get rid of Marvin to get the larger female block off of him. After Conker feeds Marvin three pieces of Cheese from the "Cheese Farm", the mouse explodes into a bloody mess.
At the end of the game it is shown that he had somehow survived getting blown to bits and has been sewn together, still hungry for Cheese and now standing beside his new king.
