Will Sal's Papi destroy the universe? Papi, a calamity physicist, believes he has made a breakthrough that will let him close all the wormholes Sal and Gabi have made in the membrane between universes. But how will that affect Gabi's baby brother, Iggy, who needs to be connected to another universe in order to remain healthy? And what will it mean for Sal, who uses the holes to stay in touch with other versions of his Mami Muerta? As if he needed more problems, a Gabi from a far-off world shows up determined to stop Sal's papi at any cost. She believes that sealing all the holes will only bring about utter destruction. It's already happening in her universe. While Sal works to keep both Papi and this other Gabi under control, he has to worry about finding a new home for Yasmany, and he's also tasked with co-directing Culeco Academy's performance of Alice's Adventures in Wonderland for parent-teacher night. It's a lot for one guy to juggle, even if he is a showman. Good thing he has some help - a multiverse full of friends and a few clever AIs. Wait...did that toilet just talk?
