In the first season of DBZ when Vegeta fought Goku he threw an artificial "moon" in order to transform to a monkey. What Iam suggesting is that in the maps there should be an item that gives you the power to create this "moon" and thus transforming you into a monkey. Obviously you would be REALLY powerful and also REALLY slow. In order of fairness it shouldn't last very long and the item should only apear like once or twice during the map.
PS: The quick way of forcing the monkey to go back to normal would be pulling its tail or cutting it with a beam.
