Petey is Mrs. Ramsey's pet pig and mastermind. He has intelligence no other animals have.
- Master Thief: Mrs. Ramsey trained Petey to follow her commands and be a thief.
- He knows how to use some devices.
- He replaced a ferret that wasn't intelligent or strong enough to be a thief.
- He is similar to Otis from Lab Rats in that he was an innocent-looking pet that Kaz/Adam likes and takes in, but Bree/Chase doesn't approve for their own reasons. However, they find out that Petey/Otis was evil and working for a villain, and is stronger than the average human.
