The unpoked cresbot is an unlock item for the Cresbot pet. It can be poked to obtain the pet. The cresbot is dropped by any of Cres's automatons.
It is possible to receive two Cresbots in a single kill, if the player is wearing a Mask of the Automatons. Although, this would be exceptionally rare, as the player would have to receive the very rare Cresbot drop on a 10th kill in order to activate the drop-doubling benefit of the mask.
