Oh gee, an issue of a comic where a character(s) escapes from a world they imprisoned themselves in, and shenanigans ensue. Never seen that done before.
Also, this series is over, so what is the moral lesson of the day? That Gronk is a very precious creature, and that you should all respect him. I don't know if his name actually is Gronk, but that is the noise be makes, so fuck it, he is Gronk now, and I wish he survived Rick and Morty destroying that machine.
