Mel is a former E.V.O. that lives in the Petting Zoo. Its tongue appears to be made up of three tentacles and it seems to stay in the water. After the Worldwide Cure, Mel returned back to being a crocodile.
Mel first appeared when attacking Rex in the Petting Zoo after he was racing around, taunting most of the E.V.O.s 
Again, he appeared after the six month gap, but only to be controlled by Providences' collars.
- Another E.V.O. similar to Mel is seen being used in the Providence Basic Training Cage, most likely one of her babies.
- Several infant E.V.O.s similar to Mel are seen when Rex and Noah were trapped in the Petting Zoo, which according to Rex are her babies.
