When she was younger, she baby-sat Max for five years, and he always believed that she was trying to choke him to death with baby powder when she was actually changing his diaper.
Some years later, Debbie came to visit her uncle and cousin, where she agreed to pretend to be Max's girlfriend in order for him and his friend P.J. to get into Burger Behemoth, which they were constantly being prevented from entering by Duke and his gang The Pharaohs. During this plan, Duke took a liking to Debbie and tried to seduce her, but failed.
After Max defeats Duke in a skateboarding race, Debbie joins him and P.J. in eating at Burger Behemoth whilst a defeated Duke looks on from afar with his gang.
Debbie was voiced by Kath Soucie.
Debbie is shown to have tan fur with auburn hair, and she wears an orange top with a blue jacket, light blue jeans and brown knee-high laced boots.
When she was younger, Debbie wore a black top and had her hair tied up in pigtails.
- It is unknown what age Debbie is, though it is safe to say that she is at least around 16-18 since she is old enough to drive a car.
- It is also unknown whether Debbie is related to Max through his mother or Goofy.
