Rocketship

It's a flying rocketship from outer space, aliens fly in it, a King Alien. He cages the owners from the boys, Jimmy's one is in the aliens with put green in those and there's a big giant bird too.

Now the owners are alive, now the kids steal the aliens' rocketships. All of them. Now they have guns on their rocketship, big guns.

The green bit on the back is the engine, it's very small, but it flies very far.
The white pointy bits are the guns.
