The yellow box is contained with a space police laser. It opens on hinges. The chain is not really holding the box on the ship, the box is connected to the ship. The minifigure is holding a thing that shoots out the green piece.
This is a set that my Dad bought that can be reconfigured to build three different houses. The top comes off and you will see the stairs that lead up to the attic. The grill has a chicken leg on it and there is a picnic table. There are also flower boxes and a sidewalk. There is a truck that carries flowers. There are four minifigures living in it. I started it in the afternoon and finished it before dinner time!
These are snakes that I made. The yellow and white ones slithered through soap and some is still stuck on them. The soap is white lego pieces. My favorite one is the little brown one, and the one with the angry eyes.
