Dusty the Vacuum sucks up stuff and spits it out again.
If you press the space bar while holding Dusty he'll turn on and suck up whatever is under his nose.
If you press the button on his nose, it will change from 'S' to 'R' to 'E' and then back to 'S'. S is for suck, R for reverse to spit out things previously sucked, and E for erase. SHOW ME
If you are in a house when it blows up then Dusty will suck up everything on the floor.
For advanced users there are also special keyboard commands and mouse buttons you can use while holding him. Also you can set the size of his stomach.
