At the fair, Schadenfreude once again manipulates Eva into striking him, activating her evil bone and turning her into a mindless killing machine. He unleashes the monster on the Science Fair where she destroys all the Evil Inventions whilst singing Annie's "Tomorrow". Brain and Scamper help Igor escape from the plant and learn that Malbert had deliberately killed Malaria's crops with a weather ray that created the storm clouds so he could implement his "Evil Inventions" plan, thereby keeping himself in power. Rushing into the arena, Igor tries to reason with the enraged Eva while Brain and Scamper power down the weather ray. Eva roars furiously at Igor until the sunlight begins to shine once again on Malaria, which permanently deactivates her evil bone and returning to her sweet and gentle self.
