Little mousie has just stolen a piece of pizza and left the kitchen through the magic portal in order to find a quiet corner to enjoy his meal, but now finds itself in a prehistoric world, where it finally sets about devouring its hard-earned pizza with relish. But oh no: danger looms once again!! Some nastyy T-Rexes want to steal her prey (or probably just eat her right along with the pizza). Then rescue appears in form of a new magical portal opening — right in the middle of one of the dinosaurs’ mouths — will Mousie dare to go through it? and if so - what lies ahead?
