Here are the instructions on how to get to it:
Secret Level
About halfway through Level Ate, you will find three sets of forks positioned just to the right of a horizonatal piece of bacon. Use the Snott-Chute to float between the bacon and the left fork. You will enter a secret level called ''Forked.''
Not really a "cheat" cheat, but it's a secret level from an old but amusing game and that description amuses me to no end.
