Fallen from above: Eddsworld X Undertale crossover

Get ready for some trash in this book, alright m8?
Edd, Tom, Matt and Tord were walking by for a stroll after a zombie apocalypse. They were about to go home since Edd ran out of Cola, but then spotted a mysterious looking mountain. Matt said those who climb the mountain never return, and Monsters live underground. Tom disagreed with that notion, Monsters aren't real right?
RIGHT?!
...Right?
