Moby Duck

The giant fowl Moby Duck is a scourge of the sea and a machine controlled by Jimmy's mother Mrs. Dirt, who had been trying to make him take a bath for 36 years.

History
Moby Duck will relentlessly pursue anyone whom it deems unclean until such time as it can clean them as a powerful battleship. After Cree Gekko goes with Numbuh Dickson and his Grandmother, his grandmother learned the truth behind Moby Duck: that it was actually a robot controlled by Mrs. Vanessa W. Dirt. Mrs. Dirt was defeated by Paul's Mobile Duck with the Super Wrench causing Vanessa W. Dirt's butt to be burnt and went out and flee from Numbuh's Fleet's hugging ability that can easily crush Moby Duck.
