This blog has guides to all of the newer shows and parades. I'm sorry to say, it looks like this one in particular is gone forever. This was a show put on at the Odyssey and was part of a character dining experience at EPCOT Center, back when there was a big push to make the park less educational and more fun. (it obviously didn't work out that way)
The character show featured our favorite friends as galactic explorers and even though these photos are from 1991- the retro style and costuming is so painfully 80s. It looks like Mickey mouse and Rainbow Brite had a few babies- Or pets. One thing the Show didn't have was Donald Duck- it was never explained how he somehow was less important than Chip and Dale, but I suspect Donald refused to wear that outfit.
