Ferguson "Fergle" O'Reilly is the brother of Mom, and Dexter and Dee Dee's magic uncle. Him, Mom, Dexter, Dee Dee, and Grandpa may be Irish.


Fergle O'Reilly is a short man, just a little taller than Dexter, and has curly red hair (a little darker than Mom's) and black eyes. He wears a formal white shirt and tie with a green jacket, pants, shoes and hat. His overall appearance makes him resemble a leprechaun (which he may actually be considering his unique magical abilities).


  • He is based on the comedian Ed Wynn.
