Jump on the switches that will take down the statue that Elmer is standing on. Once this is done, go nearby and he will try hitting you with his hammer. Dodge him and his hammer will get stuck in the cement. This will give you time to kick him, and he will drop his hammer. Hit the switches around the cage that holds the Time Gem. Do this to all the switches and the cage will break. Once done, Elmer will fall of the cliff and Daffy Duck will take the Time Gem and it will warp him to Babba's Cave.
