After the Halloween episode "Happy Howl-O-Ween", which was the 30th episode, the show went on a hiatus until August 2013.
Are you fucking kidding me!?
This show was on it's way to become the #1 highest rated show in the world. Dudley Puppy was going to be up there with Mickey Mouse, Bugs Bunny, Homer Simpson, Scooby-Doo, and SpongeBob. However, the jerks at Nick were like "This show isn't getting SpongeBob ratings" and the show aired new episodes in August 2013 at 1:30PM, which is a shitty timeslot and worse of all, it was Weekdays so they were burning it off
