Toxic waste from the Chemical Plant seeped into Nige's soil through the river and mutated his vegetable crop into the Veg-Heads. Nige was captured by the Veg-Heads' leader, King Edward, along with Sonic the Hedgehog and Harry Mole. Sonic managed to free them all, but Nige was so irate at being humiliated by his own vegetables that he charged at them and was subsequently captured by the turnips. He was again rescued by Sonic.
