The portal to the multiverse flashes a bit before turning on as an excited Penn, Sashi and Boone reach the room. They try to discuss what to do first, but Phyllis simply pushes them through the portal and they end up in a dimension where Penn is Santa, Sashi's an elf and Boone's a gingerbread man.
After that, they zap up through some more portals, ending in an underwater realm as mermaids-or crab person in Boone's case- before goiing through another one, turning into cereal mascots. They keep doing this until they return back home, where in Rippen and Larry, alongside some more interdimensional enemies, rush after them.
The trio simply get ready to fight back before suddenly swapping dimensions and turning into magical girls, Penn and Boone included, and use their wands to blast their enemies away.
In a dark room in the middle of nowhere, Sashi and Penn fall to the ground safely while Boone hits it face first, and it suddenly lights up to see some of the bad guys and allies they had during their journeys, which is followed by the trio flying up, turning into robots and shooting a beam at the screen, forming the title of this fic.
