Umm...Why don't we just give DO free reign to put any creature he wants into MitP? It looks like that's what's going to happen anyway. No wait, then we'll have necromantic tentacles growing out of ectoplasm which is, itself, an intelligent being capable of sucking the life out of the very grass and turn it into an undead horde to take over the multiverse.

ANYway, MitP vote: yes.
