What am I? I really want to know!

Some think I'm a turtle, cuz in mario kart, I start out slow!

And yes, I have a shell so as for evidence, that's even more!

But on the other hand, in the mario movie, I was portrayed as

part-human part-dinosaur! Some say I'm a kappa, some say I'm a koopa, some say I'm just a big fat loozah!

So as for who I am, I guess I'll never know! I breathe

fire like a dragon, and last week I stubbed my toe! But I

know one thing, I'm a monster, that's for sure! And I'm

ferrocious and evil and awesome! And no, I don't have fur! So

basically, I'm almost whatever you want me to be! I can be a

turtle, a dinosaur, a dragon, but I'll never be a flea!
