Bobby Pickett makes a brief cameo near the end of the film; his hit song "Monster Mash" is mentioned in one of the musical numbers "Transylvania Twist".

Troiano and Zahn had previously written new music for Pickett's 1995 film adaptation of Monster Mash.

[7] Two bats who live at Holiday Hill Farm, bug-eating Boris and bug-loving vegetarian Bella, discover an unusual sight in the pumpkin patch and rush to inform the farm's scarecrow, Jack, of their find, which is a young, innocent pumpkin named Spookley, who is unusually square-shaped instead of round.

The farmer is charmed by Spookley's unique shape and decides to make the square pumpkin his own personal jack-o'-lantern.

It includes "The Boo Song", recorded by Rick Jones, Terrence Scammell, and Bruce Dinsmore with lyrics by Zahn.
