Gummy Worms appear as a collectible item in Papa Louie 2

Papa Louie 2 Edit
There are 5 Gummy Worms in Level 5 (Mount Monterrey) that needs to be collected for getting a Warp Key. The skill required for collecting them is Ground Pound. It has been revealed in Quinn's Q&A that according to Professor Fitz, they are not native to Mount Monterrey and they actually originated from Gummy Grotto. They are the favorite food of Lettuce Larksand it's probably them who brought them to the mountain.
