Spydorz are small creatures in the first game that attack Chibi-Robo, draining his battery life. They appear after you talk with Jenny in the foyer at night, and can be defeated with the Chibi-Blaster. They drop Moohla, and additional Moohla and Happy Points can be gained by cleaning up the oil stains that they leave around the house.
Queen Spydor is the main boss of the game. You can defeat her by shooting her with the Chibi Blaster.
