Derg

'''Derg is a dog-like creature that comes from Lemon Head's home planet. Derg likes to eat slimy creatures, and once he sees a slimy creature, he loses his mind.'''

'''Like a dog, Derg is very loyal to his master Lemon Head. Derg was first featured in the video "Derg." In this video Derg comes in a package that fell from the sky. Once Lemon Head reunites with Derg, Sherman and Slimey appear wondering what Derg is. Before Lemon Head can explain, Derg eats the two. '''
