LOL Why don't I remember Jake eating a sandwich on Ice King's face? The two scenes go nicely together and I'm really surprised by the gradient in the clouds! I had a hard time making my gradient look so smooth like yours.
That side is from "Thank You" episode, were the snow gollum adopts the firewolf. Finn and Jake are trying to get to the ice king who is encased in ice. They break him out, tie him up and eat their sandwiches while watch the gollum and firewolf play.
