In the spirit of cards that reference themselves, even if it's not animal-themed:
Banquet$5 Action
Trash this. Gain two cards each costing $5 or less that are not Banquets. Put them on top of your deck.
__________
The first iteration of this didn't have the self-reference (but did set gained cards aside until the clean-up phase to prevent instant pile-outs with Lost City), and was tested on a Kingdom with Treasury. After the opening moves, the game went something like this:
Play Banquet, gain Treasury+Banquet, buy something. Pass.
Play Treasury, Play Banquet, gain Treasury+Banquet, buy something. Pass.
Play Treasury, Play Treasury, Play Banquet, gain Treasury+Banquet, buy something. Pass.
Play Treasury, Play Treasury, Play Treasury, Play Banquet, gain Treasury+Banquet, buy something. Pass.
until both piles were quickly empty.
The effect above would be less extreme with non-Treasury 5-cost cantrips as they'd be discarded after the first use, but getting a second Banquet as one of the options is generally still a no-brainer.
It's still
theoretically possible if you put a Ferry token on Banquets when Band of Misfits is around, but at that point it's just a legitimate multi-part combo of the type that Dominion already has plenty of examples, and there's generally better things to do with a Band of Misfits/Ferry than this anyway.
