What if, instead of just one SOUL falling into the Underground, 6 other SOULs fell in too? And what if those six SOULs just so happened to be characters from various animated series that we are familiar with?
This is a long, and I mean long crossover comic which includes characters from Undertale, Invader Zim, Gravity Falls, and Over the Garden Wall. The six other SOULs are Dib, Gaz, Dipper, Mabel, Wirt, and Greg.
Dipper and Mabel plan to explore a mysterious mountain near the town, and are joined by Dib and Gaz as well as Wirt and Greg. After meeting a strange kid, all seven of them find themselves falling into the Underground, and must now find a way out and solve the mystery as to how they got there, and how to save Monsterkind.
And also, why does it feel like everything keeps repeating itself? Over and over again?
