C-3PO and R2-D2 encountered several of these creatures while lost. One of the creatures fired a blaster at the droids, and then asked for food in a language the protocol droid understood. Threepio gave the alien a bowl of C-3PO's cereal, which he liked and then demanded more of. Several others of his species then approached the droids looking for cereal as well, alarming C-3PO.
The droids encounter several members of the species.
This alien species only appearance was in one of the television commercials for C-3PO's cereal. Only one of the aliens spoke, but several others of different sizes appeared.
