Casper the Friendly Ghost Big Book #3

Casper and the Ghostly Trio stumble upon a house that radiates cheer—too much cheer—leading them to suspect something’s off. What starts as a lighthearted detour quickly turns strange when Casper stays behind and uncovers a hidden nightmare: gremlins forcing Dr. Grin to craft tiny, cursed carburetor specks.

Casper and the Ghostly Trio pay a visit to a house that beams with cheerful charm, but something’s off beneath the painted smile. As the trio departs, Casper uncovers a hidden nightmare: gremlins are forcing Dr. Grin to craft carburetor specks in a grim, underground workshop.

In "How to Smile," Casper the Friendly Ghost and the Ghostly Trio stumble upon a house that seems too cheerful to be real—until Casper uncovers a far more sinister truth behind the grins. What looks like a sunny day turns into a spooky mystery when he finds that the cheerful facade hides a secret: gremlins are forcing the reclusive Dr. Grin to produce carburetor specks, and Casper might be the only one who can help.
