I'm looking for this movie that me and my sister watched all the time when we were little, I really don't remember all that much about it. I know that it is very rainbow brite esque. It was set in space and that there was a space horse that escaped and turned evil or something. The horse's name was Andromeda. Someone please help me figure this out!

Found it, it's called 'moon dreamers' and is was a series not a movie. I found it by chance in my basement.

Thank you so much for this q me and my sister have been going mad for the past few days trying to find it thank you
