Orange and Purple-Spotted

How came to be
such an orange beast as thee?
The purple spotty skin
of your strange kin?

Your roar is like screeching
Over long distance, reaching.
Your looks great and mighty,
Though they be frightening,
Are actually quite funny to see.

Sporangeasaurus be your name,
Though we do not know how that became.
You have teeth and claws in your command,
The funniest carnivore in the land!
