This is to unlock the achievement in Eets Munchies called Exotic Cuisine which requires you to complete a workshop created map. This map only requires you to press go and then it will complete itself, therefore very easy and quick....

This is pretty simple with how I've placed the objects. When your character falls it will run into the pig, once it barfs simply inhale the barf with the whale which it heads straight to. A very quick unlock for an otherwise impossible achievement....
