In Banjo-Tooie, he is the much bigger and fatter kid who begs for a burger once you find him in Witchyworld. Once fed, he becomes too bloated to move, so Banjo must use the Taxi Pack ability to get Groggy to his mother, who isn't too happy about her son eating so early. So she hits her son a few times with her purse, sending him running. Later, in Hailfire Peaks, he is on his bed. He will thank you for the burger and then inform you that he has to go to the bathroom, but is too fat to move. When talking or not interacting with him, he will rock back and forth, scratching his stomach, belching or farting.
