This series features characters known as Dee Bees. Legend says these creatures visited Disney Land secretly in the night and loved it so much they decided to live there. They take elements of the park into their looks because they're so proud to live there. These pins were designed as a bit of a joke, but the team reportedly had a lot of fun doing them.
They were released as part of the Hidden Mickey collection in both parks. It could only be found through trading with cast members in the park.

This particular pin features a Dee Bee named Rocketee, who dresses as an astronaut for Rocket to the Moon. His outfit included a space suit and helmet. His whole outfit is gray. The helmet has an antenna on the top and his suit has a large Mickey head shape on the torso. He is smiling with his mouth open and his hands are up in a thumbs-up gesture. His left hand has the "hidden Mickey icon" on it.
