Peg Puppy is Dudley's overprotective mom. She's a bit nervous about Dudley being an agent, but she wants him to do what makes him happy. Now, if he'd only wear pants…
She once dated Verminious Snaptrap and The Chameleon. In Snap Dad, she’s shown to not have a husband, which shows she's either divorced or widowed. In Mom-A-Geddon, Peg disapproves of Dudley's occupation, but after seeing him in action, she allows him to keep his job. She thinks that Kitty is Dudley's secretary, and never gets her name right by calling her Mitzy. In The Wrong Stuff, she usually nags Dudley in a stereotypical motherly manner when he's home.
