- "I say! I say! Are you looking to get work making crazy contraptions and goofy gadgets? Well, call me! At Wacky Wally Wackford's Wacky Idea "Factory"! Where YOU can make the things and I make the money! Please, I'm very desperate!"
- ―Wally, in his commercial
Wally is a carny-like Imp with muted crimson skin, curled black and white horns, a pointed tail, white hair, and black eyes with yellow sclera. He also has a long curly mustache.
He wears a white shirt, gray vest, black bow tie, white pants with gray stripes, and black boots.
In "C.H.E.R.U.B", Wally wears a top hat with a pale lavender gray stripe.
Wally Wackford is an inventor who likes selling his products for money. He runs a company called Wacky Wally Wackford's Wacky Idea "Factory" where people invent stuff, and he makes money off of their profit. He is also a torch seller at Loo Loo Land. He is also shown to be a bit goofy since he was the only one laughing after making a lame pun.
- He speaks with a stereotypical Southern accent, similar to Foghorn Leghorn from Looney Tunes, even right down to starting his commercial with saying, "I say, I say", which Foghorn Leghorn was known for.
- His design was inspired by the old-time hucksters and snake oil salesmen.
- Like Robo Fizz and Verosika Mayday, he pronounces the "O" in Blitzo's name.
- He shares the same voice actor as Cletus and Travis, with the three of them being voiced by Don Darryl Rivera.
- At first, there was going to be a laughing soundtrack for him at the end of the episode, “C.H.E.R.U.B”, but then there was a problem with the audio, so they decided to make him laugh at himself.
