It may be puppets but if you dont watch this you are a muppet! lol.
I was lucky enough to watch this when i was a kid and remember loving it.
I remember the ship turning into a robot and the hero (shiro) and his love intrest Princess Lamia, and then my next to favourite characters her body guard (who reminds me of chewbacca from star wars) and of course the robot PPA.
The action all takes place in space on the ship of the X-Project as the try and stop the evil forces of the Imperial Fighters. As with battle of the planets the crew of X-project have a secret weapon... a ship that can transform into a robot fighter. it is like both star wars and bsg, so if you like them give it a try. Also if you like red dwarf and star trek have a watch:)
