All-Terrain Attack Vehicle

AT-AV (short for "All Terrain Attack Vehicle") was the nickname of a pet pittin belonging to one of Princess Leia Organa's foster aunts, Tia (Alderaanian).

As a child, the princess had named the creature herself, most likely based on its likeness to a war vehicle with that name. No further information has ever been given on the source of its name.

The pittin was pale and had a "candy pink" color to it. It was small enough to fit in Leia's cupped hands.
