Heidi

A drive-in favorite, this sci-fi classic follows teenagers Steve and his best girl, Jane, as they try to protect their hometown from a gelatinous alien life form that engulfs everything it touches. The first to discover the substance and live to tell about it, Steve and Jane witness the blob destroying an elderly man, then it growing to a terrifying size. But no one else has seen the goo, and policeman Dave refuses to believe the kids without proof.

Loner Mark Lewis works at a film studio during the day and, at night, takes racy photographs of women. Also he's making a documentary on fear, which involves recording the reactions of victims as he murders them. He befriends Helen, the daughter of the family living in the apartment below his, and he tells her vaguely about the movie he is making.

Alex, a boy obsessed with scary stories, is trapped by a witch in her modern, magical New York City apartment. His original hair-raising tales are the only thing keeping him safe as he desperately tries to find a way out of this twisted place.

After going their separate ways, Scooby-Doo, Shaggy, Velma, Daphne, and Fred reunite to investigate the ghost of Moonscar the pirate on a haunted bayou island, but it turns out the swashbuckler's spirit isn't the only creepy character on the island. The sleuths also meet up with cat creatures and zombies... and it looks like for the first time in their lives, these ghouls might actually be real.
