Saving the planet is dirty work, but for full-time heroes Jake (the dog) and Finn (the human), cleaning up is even messier business in this week's Adventure Time #4 by Ryan North, Shelli Paroline and Braden Lamb. Boom! Studios has provided us with a look at five pages from the new issue, which features variant covers by Chris Houghton (Reed Gunther), animator Kassandra Heller, Scott C. (Double Fine Action Comics) and Adventure Time creator Pen Ward's mother, artist Bettie Ward. The issue also features a backup story by Chris Eliopoulos. Check out all four covers, plus the five preview pages from Adventure Time #4 after the jump.

From Boom!'s official solicitation info:

Oh My Glob! The Latest Super-Cool Issue of the Hit Series! Finn, Jake, Marceline, Princess Bubblegum and even Lumpy Space Princess have banded together to stop that jerk the Lich from throwing all of Ooo into the sun! It's gonna take a lot more than a sweet punch to knock this guy out - luckily, Finn and Jake are on it!
