It's the most important moment of Lumpy Space Princess's life, and it's all going to-slip through her fingers if she doesn't get help. Tree Trunks comes out of her mystery filled retirement for one last job as she agrees to help LSP on a wild west treasure hunt. Finn and Jake secretly follow along to protect their friends but discover that LSP knows more than she is letting on about this particular treasure.
