During the game's end credits, an infinite lives cheat code involving pressing several impossible button combinations at once can instead be activated by wetting your finger and rubbing against the empty Control Port One on a Commodore 64 keyboard, tricking the game into thinking these combinations are being performed. A large sprite of Maximus Mouse (from the games Summer Camp and Winter Camp) will appear, waving his arms as you rub your finger across the port until he turns grey and the Fuzzy Fountain in the background begins to flash, both indicating the cheat has been activated.
