Just a sketch I made of my happy endo-friendo T-Rex, Gertrude that I tend to use for a reference.

Gertrude's a friendly T-Rex who lives in a Jurassic Park style theme park called Mesozoic Safari. She's sapient and loves to chat with visitors and staff at the safari. She's got a bubbly personality and a thick Tennessee dialect that she learned from her 'father' (the genetic engineer who made her).

She, like all prehistoric creatures at the safari, has been engineered to be able to swallow guests whole without hurting them. She can turn off her digestion at will, and loves to have friends curled up in her belly.

She also loves to hug, which she does by belly-flopping on top of the person she's hugging. Because her belly is so plush, this doesn't actually hurt.
