Mum is a character that appears in Sonic the Hedgehog in the Fourth Dimension. She is a sauropod dinosaur whom Sonic and Tails encountered in pre-history.[1]


Mum is a large sauropod with a wrinkled neck and enormous lips.[1]


Mum lived in prehistoric times, and was tending to her nest when Sonic and Tails suddenly appeared. She then decided to treat the two of them as her babies, licking Sonic on the way. Tails decided to call her "Mum", and began to converse with her. She was then scared away by a Utahraptor.


Mum seems to be maternal, and she seems to be a very cheerful dinosaur. She likes to lick her babies.[1]
