Rex Vector and his assistant, Mr. Pete, return to Pine Tree Mountain with their terrible invention: a robot monster with the abilities of real animals. In order for the robot to function properly, Vector must find power sources that are concentrated in crystal shards, which are lost somewhere near Pine Tree Mountain. Vick, Briar, and Bramble learn that the crystal can turn objects into living creatures.
