Was literally thinking the Rick & Morty tie-in would be that Morty gets a pet cuttlefish who not only speaks, but insists that even though he is stuck in this aquarium, he says it is preferable to the pathetic existential prison of their inferior human minds, and he uses his mesmerizing persuasive power to turn the rest of the house into a hippie comumune of drifters who do whatever he wants, and ultimately directs them to attack celebrities. The cuttlefish's name is Charlie.

Recurring villain, probably gets his own show.
