Hanna-Barbera All-Stars: Elroy's Rescue is a simulator ride featuring the Hanna-Barbera characters such as Yogi Bear and Boo-Boo Bear. It is located at Hanna-Barbera World from Cartoon Network Land in Burbank, California and Warner Bros. Movie World in the Gold Coast, Queensland, Australia.
The ride's premise is that the riders have to ride a spaceship driven by Yogi and Boo-Boo through the Hanna-Barberaverse to save Elroy Jetson, who was kidnapped by Dick Dastardly and his sidekicks Klunk, Zilly and Muttley.
It shows Dick kidnapping Elroy on a TV after Spike Brandt and Tony Cervone (in live-action) telling him that Hanna-Barbera's other stars' fanbases are significantly bigger than his and then it shows Yogi and Boo-Boo telling the riders that they have to save Elroy.

- Since Dastardly had kidnapped Elroy because of The Jetsons Movie in the original ride, it was changed to Dastardly's disappointment of his fanbase being minor in comparisation with other Hanna-Barbera's franchises (like Scooby-Doo and The Flintstones).
