This is Spiderman's 'robot spaceship' that is really cute.
He did this 100% by himself, and is zooming around me with it as I type this post! He has parked it next to the mouse. (At least he hasn't left it next to my bed on the floor so I step on it as I get up in the morning, or next to the toilet, or outside so it gets wet... I could go on and on so best to stop now.)
