Pizza Cake! is a mission in Grand Theft Auto 2 given to protagonist Claude Speed by Elmo of the Loonies. The mission is available from the bottom of the two green Loony phones in Fruitbat of the Downtown District.
Elmo is upset that Pizza Cake keeps messing up his favorite food. He wants Claude to destroy one of their restaurants as punishment. Claude does this but the effects are underwhelming so he orders Speed to destroy the delivery van instead.
The reward for completing the mission is $20,000.
