Scooby-Doo is a talking dog, Shaggy's best friend, and the mascot of Mystery Inc. He originally met Winnie the Pooh, Piglet, Tigger, Rabbit, Eeyore, Owl, and Gopher in the first (and, for so far, only) episode of The New Winnie the Pooh Movies entitled The Pooh Mysteries (which featured the Scooby-Doo, Where Are You! pilot episode What a Night for a Knight). Pooh's Adventures of Scooby-Doo! The Mystery Begins will truly explain how Pooh and his friends first met Scooby-Doo and the gang.
- Scooby-Doo is voiced by Don Messick (1969-1997), Scott Innes (1998-2001), and Frank Walker (2002-present)
- Scooby-Doo will first meet Tino Tonitini and his friends in Tino's Adventures of Scooby-Doo! The Mystery Begins.
