Mantis Tractor

From the movie Coraline

In the seemingly ideal Other World, the Other Father drives a mechanical praying mantis tractor. It spits out seeds and water as it crawls around the garden, and it cuts down plants with it's forelegs, making it a great gardening tool. Although controlled by the Other Father, the mantis tractor appears to be semi-autonomous.

Being a mantis, it could also get rid of pesky aphids.

The mantis tractor also has a rotor than lets it fly into the air. Not sure how often a gardener would need that, but it's always great to have options.

Later on the mantis tractor fuses with a pumpkinized Other Father and a pair of of mechanical, piano-playing hands in an attempt to stop Coraline from retrieving a child ghost's eyes. The Other Father, not wanting to hurt Coraline, broke free long enough to give her the ghost eyes (which where contained within the mantis tractor's gear shift) before plunging the contraption and himself into a pond to their deaths.

The Other World also features insect-themed, semi-autonomous furniture, which take a dark meaning as the Other Mother reveals herself to be an evil spider-like witch.
