Peegee was a very sad Fakegee who was constantly being bullied about his name.
After surviving The Fakegee War, he decided to make suicide.
Before he made suicide, he killed off the Dranquilis species. Shortly after he died, he was famous because of him killing them.
Usually, he would sit against a rock and cry every day. This was how he would supposedly make himself feel better. But it didn't work.
Poor Peegee.
