Do you think that the teenage mutant turtles master splinter is a rat or a beaver?

Ok, if you are over 12, this is a really stupid question. If not, then I really have no idea because I have never seen tmnt. I do know however that rats and beavers look NOTHING alike. For one thing, beavers are waaaaaaaaaaaaaaaaaaaay bigger. They are dark brown in color and have huge flat paddle tails. Rats have thin long tails. Rats are much smaller and cuter. They can be just about any color and have tiny pink feet.
