Grim and the pups race against time to stay in the real world. But Grim isn’t going without a fight, and he’s never stronger than he is on Halloween...

Freddie Hazel and his family move into Maplecrest Manor, where they find three cute pups who were tricked into becoming ghosts years ago.

As Halloween approaches, the pups are running out of time! Desperate to catch Grim, they follow a tip from Madam Maples to the town's haunted corn maze.

As Freddie becomes a basketball star at school, Piper worries he's forgetting his mission to help the pups. Fox grows suspicious of Freddie's abilities.

Piper and Freddie discover a portal to another world in the séance chamber at Maplecrest Manor. Unfortunately, so do the ghost hunters!

Amateur ghost hunters Cleo and Edwin invade Maplecrest! As the pups find ways to scare them off, the kids try to unlock the mystery of the key.

The latest attempt to restore the pups ends up transforming Piper into a ghost! To change her back, Freddie and the pups seek the help of an expert.

The pups temporarily turn back into their real selves and spend the day doing things they can't do as phantoms — which puts them in grave danger.

It’s time for a home inspection at Maplecrest, but the repairs are a disaster. The kids and pups must make sure the family passes with flying colors!

The pups head to school to warn the kids that Freddie's parents are ready to give up on the house and move. But the ghost nappers are hot on their tails!
