Out of all the reappearing monster punching bags in the Final Fantasy series, which is your favorite? Would it make a good pet, or did you just enjoy fighting them a lot?

I personally like the Tonberries, despite their crazy knives...I wouldn't keep it as a pet exactly, it'd be more like a body guard. I'd be too afraid to let it sleep in my room at night like a cat, I might wake up with a 9999 dmg stab coming my way!
