History[]
Post Cereals commercial[]

Monster trio caught.
After entering a dimly lit Post Cereals factory, Shaggy and Scooby narrowly, and accidentally, avoid attacks from the Post Cereals monsters. First, lunging out from behind a stack of Waffle Crisp cereal boxes, the Zombie Granny attempts to grab the duo, but trips and falls through the boxes instead. Further along, the O's Bull readies to startle the pair, positioned in their line of sight, but as Shaggy turns his flashlight, he's blinded and stumbles off in another direction. Finally, the Ghost Bear leaps off an upper level, in an attempt to crash down on top of Shaggy and Scooby, but a carton of Golden Crisp cereal boxes are swung in its path, which it smacks into instead. In the end, once Shaggy and Scooby have noticed the trio of monsters, they've all been adequately impaired enough that the pair have no problem posing with them.

Notes/trivia[]
- As there is no unmasking, it is unknown whether or not these monsters are fake.
- The Zombie Granny and Ghost Bear are modeled after the Waffle Crisp granny mascots and Golden Crisp's Sugar Bear, respectively.
