Oh, I'd really rather not. Domesticated animals are exotic enough for me. But if I must...I'd obviously get a Komodo dragon. I don't know why anybody would bother with any other fantasy pet. They bite things and wait for them to die, then they feast on the infected flesh and continue the cycle by keeping a horribly bacteria-ridden mouth. They're like politicians in this and many other ways.
