Goose Lake Monster

The Goose Lake Monster was supposedly sighted at Goose Lake.

Scooby-Doo! Stage Fright
Velma Dinkley read about the Goose Lake Monster in Acme Gazette as Mystery Inc. was leaving Chicago. This led to their next mystery and cut off Daphne Blake and Fred Jones's awkward attempt to reveal their feelings for each other.

Notes/trivia

 * It sounds like a parody of the Loch Ness Monster.
