I had a Nugget figure as well but his leg broke off. I don't really collect them but i would like to find a good Nugget to replace him. There is not much you can do with a robot that turns into a rock as a kid (throw it at my brother?).
My brother and i really looked after our toys. My mates kids come over and play with my Lego, Matchbox cars and Micro Machine collection and have a great time. They know not to be rough with them though or they go away.
