Billy Buggy

I suppose Billy Blastoff was meant to be your little brother's Major Matt Mason but I played with them both no problem. I loved Billy B and have fond memories of his various sets. I'm always amazed when something completely leftfield turns up like this spanish Billy Blastoff Beach Buggy by Nacoral. Billy has his flippers on so I assume it's part of the wider Billy Scuba Diver range. I wonder if his backpack powered the buggy? The toy is available online from reader Castro. Anyone collect Billy Blastoff?
