A new novelty flask tied to Rock 'n' Roller Coaster Starring The Muppets has arrived at Disney's Hollywood Studios, available while supplies last. The clear, laboratory-shaped vessels are a nod to Muppet Labs, the fictional scientific institution run by Dr. Bunsen Honeydew and his long-suffering assistant Beaker — both of whom factor into the ride's storyline.

The flasks are included with purchase of one of two specialty drinks sold at FØØD by Swedish Chef, a quick-service kiosk located near the attraction's exit. The Pink Le-moi-nade ($6.79), inspired by Miss Piggy, blends Minute Maid Premium Lemonade with guava and shimmering glitter for a bright pink look. The Pond Water Limeade ($6.99), inspired by Kermit the Frog, pairs Minute Maid Limeade with green apple and fruit juice-filled pearls for a deep green finish.

Each flask features the Rock 'n' Roller Coaster Starring The Muppets wordmark on one side. Flip it over and you'll find the attraction's banner artwork, depicting Kermit, Miss Piggy, and The Electric Mayhem band packed into a psychedelic limousine.

Disney has noted the flasks will only be available while supplies last, so guests eager to snag one may want to make FØØD by Swedish Chef an early stop on their next visit to Hollywood Studios.
