Cooker

The Cooker is a gas cooker on wheels, complete with a coin slot and wonky antenna, who is the patroller of the moon's surface. It is shocked to find Wallace and Gromit 'eating' the landscape, but upon discovering a holiday brochure becomes captivated by the idea of skiing.

A Grand Day Out
He was a coin-activated robot that lived on the Moon. When Wallace and Gromit came to the Moon to get some cheese, Wallace activated him. He looked at a ski magazine and wished he could ski himself.

After being unwittingly activated by Wallace with a coin, the Cooker was surprised to find others on the moon. When he noticed Wallace was littering and placing his rocket on a forbidden parking spot, he tried to teach Wallace by hitting him with a police truncheon.

But before he could do so, the coin meter was used up and he stopped in the middle of the action. Upon seeing the motionless Cooker behind him, Wallace took away the truncheon and inserted another coin. The Cooker reactivated and noticed Wallace and Gromit leaving to Earth and, linking them as a potential means of taking him to Earth so he could ski, the Cooker followed them. The Cooker stowed inside the base of the rocket but accidentally lit the high fuse, which blew him off and launched the rocket.

After landing, the Cooker was depressed at having failed to get into the rocket. Then he realised the metal strips that came off the rocket with him could be bent, so he decided to use the metal strips as skis and the various hills on the Moon as ski slopes. It worked, and having fulfilled his ambition at last, he was last seen waving good-bye to the space travelers as they set off back to Earth.
