Greta goes to work with Marv, and Godcat and Devilcat watch the movie "Armageddon." Travis and Abbie follow Aidan to Heck — not Hell.

To show Travis they really love him, Abbie and Marv plan a last minute half-birthday rager. Godcat summons the cherubs to see the wonders of Earth.

Greta enters a rocket-building competition sponsored by billionaire Jefflon Bezmusk. Meanwhile, Travis moves out — and the cats get inside Marv's head.
