Wet Willie is one of Cap'n Ahab loony crew members who appears to have a strong love for water and spends all his time inside of a water barrel and making cartoonish noises. Because of this, he appears to be made up of more water than flesh. When he tried to attack Dexter, Dee Dee summoned some sea sponges which quickly sucked away all the water out of Wet Willie, leaving behind only his very confused dusty remains.
