Butters is determined to get his first kiss so his friends won't make fun of him anymore.

Kyle chooses Stan, Kenny and Butters to celebrate his birthday at Casa Bonita. When Cartman finds out he's not invited, he arranges for Butters to conveniently go "missing".

Cartman plans to learn all of Butters' innermost secrets and then use them against him, by pretending to be Butters' new best friend, a robot named AWESOM-O.

Butters must fake his death, dress up as a girl and infiltrate a slumber party, in order to retrieve a future telling device Cartman is convinced the girls have.
