Adventure Time continues with the D&D references

Jake: "Possessions: Ice Crown. Probably stolen."

Ice King: "Argh, no! I made that item! With magic!"

[a bit later]

Ice King: "Cast spell: Detect secret door!"

[later]

Finn: "I can't just beat up the Ice King for nothing, that's against my alignment."

[even later]

The Ice King brings out a game box called "Do It's and Bladders".

In the next episode Finn cooks some free gruel for poor people and adds a secret ingredient, quote: "It's a stoneskin potion. It gives your body the power to grow armour."
