This is a special Lego gun that can move, it has loads of joints and can make lots of different shapes.
I really love this one, it's a walking rubbish crusher, that has a hook for picking up junk, and a spinner for cutting big pieces. We have been watching Dirty Jobs and that man does work with loads of machines and rubbish collectors.
I made this guitar at Kinder with my friend Oscar, he made one too. It's very special and I didn't want my Mum to take a picture, but she said that it's a really good invention. My Dad plays the guitar, but this one is just for me.
