Magic Mike Robot

This was one of my favorite toys as a child, to a point of course it stopped working, but even without the battery powered features I always loved this robot.
Recently I was able to buy one second hand it doesn't move but at least it still talks and makes those incredibly annoying sounds that this kind of toys had in the 80's.
Anyway it's been a while that I hadn't made any MOC outside of the Star Wars context and probably it will require some modifications, but the objective is to make functional, although I doubt it will talk
