battletoads war-toads
EDIT: dang it, war beast requires medium size.
how about adding spell fire instead of improvised weapon.
magebred spellfire toads, 15 con, accidentally hit them w/ a spell and your toast.
EDit:
its a shame that magebred only makes them int 2, int 3 and they could take a level of warlock and use summon swarm and EB.
