74 years ago, Pip was seen with his brothers and sisters waiting to see the Halloween Hound. However, after realizing the truth, Pip refused to "visit" him, but was caught, anyway. Just as his soul was about to be consumed, the sun rose up, causing Warwick and the Halloween Hound to escape. Pip's soul became separated and it made him a ghost. After being seen by the sheriff, he told Joseph and his dad to get out of there and had the place condemned. Pip tried to tell Joseph that he was still around, but a magic barrier caused him to remain trapped inside the manor anyway.
Role in the film
74 years later, when B-Dawg enters Warwick's manor, he calls Halloween Hound three times. Pip tries to warn them but the Buddies get scared. B-Dawg thinks he is the Halloween Hound and escapes him. After Warwick and Halloween Hound are released, Pip becomes free so he can warn the Buddies. Before he does so, a boy wearing a ghost costume gets scared by Pip, and he uses it as disguise so he could warn the Buddies. Pip tries to warn them, but the ghost costume slips off and the Buddies get frightened again.
B-Dawg still thinks Pip is the Halloween Hound, and they escape him. Even so, he still does not give up, so the Buddies go to Zelda's hideout. When Pip appears, the Buddies and Zelda get terrified, but he convinces them that he means no harm. Halloween Hound then appears, but he gets stuck because he's too big, and they escape him. They go to see Deputy Sniffer, but Pip and the Buddies accidentally scare him. Halloween Hound appears again, and Sniffer tells them that he can deal with him, but he gets turned into stone.
The crew goes to the graveyard where Zelda attempts to bring Pip back into his body, but then Zelda gets turned into stone like Sniffer did, and Pip sees the Buddies get captured by Halloween Hound. Pip enters Warwick's manor, where he and the Buddies manage to reason with Hoot and tell him that he can reform. Hoot agrees and releases the Buddies, but then Halloween Hound sees that Hoot betrayed them, so he turns the owl into stone. Pip and the Buddies get trapped, but Pip bravely informs Halloween Hound that he sucked his siblings 74 years ago. Halloween Hound turns Pip into stone as well, but Skip and Rodney's rat forms help them all escape.
After Joseph destroys the crystal, Pip turns back to flesh, and Sniffer, Zelda, Hoot, Pip and Pip's brothers and sisters' souls return to their bodies, while Skip and Rodney are turned back into humans. Pip then returns to his owner and says goodbye to the Buddies before he and Joseph leave.
