Larry P. Acme was the owner of Acme Dog Biscuits, and the true identity of the Cheese Monster.

Physical appearance

Larry is a middle-aged Caucasian male with brown hair. He wears a blue suit with a white shirt underneath and a lighter blue bow tie.


He acted concerned about what was going on at the Scooby Snack factory, even offering his business rival, Constance McSnack, a job at his factory. But this was just to hide his true nature of being jealous, greedy, and selfish. After being unmasked and arrested, he was mad at Scooby-Doo because he ate his costume.


A Pup Named Scooby-Doo

Season one

Larry unmasked.

After the Cheese Monster scared off all the employees at the Scooby Snack Factory and forcing Constance McSnack to close it down, he made a news report that his company would supply the dog treats until her factory could re-open again. He then supported her after a failed investigation into the monster attacks, and even offered her a job, but he was disappointed though when she told him all the top secret formulas was locked away in her factory so they couldn't add her ingredients to his own. After the kids probed Mrs. McSnack for questions, she and Mr. Acme left in a car together.

During the kids' search through the abandoned Scooby Snack factory, they heard the ruckus Mr. Acme made and managed to see his back, fleeing around a corner. When the Cheese Monster cornered Scooby-Doo into a locked room he did the only thing he could think of: eat it neck down, leaving only the head intact, but also revealing the body of Mr. Acme and that the monster was only a costume. He tried to escape, but Velma Dinkley quickly entangled him with her yo-yo. Once the police arrived they took off what was left of the Cheese Monster to reveal that it was in fact Larry P. Acme.

A clue was when his blue suit (which he wasn't wearing underneath his costume) was found in the trash. He wanted to put his main rival company, the Scooby Snack Factory, out of business by dressing up as the Cheese Monster to scare off its employees so he was free to find the secret formula, which he wanted to use in order to improve his own distasteful recipe and take over the market. Larry then says that he would have gotten away with it, too, if it weren't for those pesky kids and that puppy who ate his costume (which Scooby refers to as "delicious," much to Larry's confusion).
