In their first appearances at Disney's California Adventure this week, bumbling scientist Dr. Bunsen Honeydew and his meep-meeping sidekick Beaker joked and chatted with guests.

They maneuvered in a silver, egg-shaped roving laboratory outfitted with flashing lights, spinning signs, confetti cannons and smoke and water sprayers.
