There's a fan-made RP book being made over at [link]
and I wanted to test it out. My friends and I have only RP'd once, and it didn't go very well, but this is Adventure Time and we're all fans of it. So after they made characters (I'm the DM), I decided to draw them all up.
Doctor Snowball, the Doctor of the group.
Pan Conquervoz, the Warrior.
Bookie, the Thief (who's also a clown).
And Pumpler, the Fire-Spark Wizard.
I love everything about Adventure Time. It's characters, story, under lying messages. It's great. Just great.
