The Superfantastic Mega-Buds 2 (Camp Lakebottom and Supernoobs Crossover)

Here's what i'm thinking some how another meteor showed up and gave mcgee, gretch, and squirt their powers again, or a villain created a portal, that takes them to where the supernoobs are, or the bottomdwellers or supernoobs find a mystical object that makes a portal, where they work together to defeat a common enemy I think anyway.
