Zim ordering the Computer to bring him the Voot Carrier.
The Voot Carrier is, as the name implies, a device meant to carry the Voot Cruiser from one place to another when it’s heavily damaged and unable to fly, making it pretty much the Irken equivalent of a tow truck. Presumably the Voot Carrier is made of a strong enough metal capable of carrying the Voot Cruiser with easy but it wasn’t strong enough to survive a collision with a bee.
The Carrier is a hovering disk with a retractable bubble-like covering on top of it, but has the ability to camouflage itself, as the Computer using a sort of remote control was capable of disguising the carrier as a pig. The physical remote was seen attached to the pig, which Zim used by pressing a button. When in use, the pig turns back into the floating disk it originally was, and once it safely gets under the Voot Runner, becomes a pig again.
The Voot Carrier was only ever seen in "Attack of the Saucer Morons".
