Velma Dinkley meets The Brain-Eating Meteor
An investigation deep in the basement of Endsville University's old abandoned science department leads one Velma Dinkley into the lair of a green gelatinous creature hungry for brains! Fortunately for the starving alien, Mystery Inc.'s resident geek girl provides him with a sweet snack, which in turn leads to her becoming his latest mindless thrall. "Sure she might it it's deranged, but she won't give it a thought after I've eaten her brain..." A crossover I saved just for Halloween between Scooby-Doo and The Grim Adventures of Billy & Mandy , two Cartoon Network favorites of mine when I was growing up.
