It's Totally Mathematical! Join Finn, Jake, and all of their friends in this second issue of the ongoing comic book series showcasing all-new adventures through the magical Land of Ooo. The boys have embarked on another crazy-cool adventure, and this one will be their longest, most exciting yet! The top-rated Cartoon Network show now has its own comic book! The Adventure is just beginning, so don't miss out on this exploding phenomenon - this is an issue that will go fast!
Finn, Jake, and Desert Princess search for a way out of the Bag of Holding. Along the way, they meet up with Ice King, who decides to have a sand-and-ice picnic with Desert Princess. Meanwhile, the Lich continues sucking up places and people in Ooo, including Marceline, who lands on an island inside the bag with Princess Bubblegum. Lumpy Space Princess also gets sucked in and lands on Jake.
Finn and Jake (with Desert Princess, Ice King and Lumpy Space Princess in tow) drill into the ground and find the fabric of the bag at the bottom. They attempt to escape by punching though it, and get absorbed by it. As Marceline and Princess Bubblegum meet up with the others, Lumpy Space Princess declares that she believes Finn and Jake are dead.

After the Show
Marceline and Princess Bubblegum are walking home from Marceline's show and talking about how it went. Apparently it didn't go as planned, but they both agree that it was "pretty awesome" when Flame Lord jumped on stage and Marceline broke his nose.
