When Peri and Entrèe accidentally cause a Whirrel to destroy half the town, Joe loses his temper, demolishing the other half. The other mutants tell Joe that he needs to control his temper. Joe, hurt, leaves, declaring Peri and Entrèe the new mayors. In solitude, Joe hears from the bird on his back, Lord Wingus Eternum, who teaches him how to control his anger.

After Lord Wingus Eturnium convinces Joe to go to the other side of the island (with "help" from Peri and Entrée) to meet with his kind, he is given a choice to have Joe separated from himself, but finds that it means having Joe ground off of him.
