Funny Farm Whack-a-Mole was apparently some sort of mini-game that was supposed to be in Crash Twinsanity. In the data of the game, it is mentioned by an unknown character. It might have been a very early version of the part in the game where Crash uses Cortex as a sledgehammer to get rid of the invading worms. Traces of this can be seen in the part of Crash Twinsanity where Crash must destroy all the worms in a Whack-a-Mole style just after meeting Farmer Ernest. This level would have also had a timer similar to the Time Trials.
