- Cross-Dressing Voices:
- This was going to be the case with Billy, who was going to be voiced by Jessica McKenna, before Aaron Springer, a man, took on the role.
- This is however played straight with Zeke's grandmother, who's also voiced by Tom Kenny.
- Dawson Casting: The main characters, all preteens, are voiced by adult actors.
- Descended Creator:
- Aaron Springer voices Billy.
- Tony is voiced by writer Kenny Pittenger.
- Fake Brit: James Arnold Taylor as Count Wretcher.
- Name's the Same: Zeke isn't the only Disney character named that.
- Production Posse:
- This show is a SpongeBob SquarePants reunion due to having Aaron Springer, Merriwether Williams (who had outlined a vast majority of Mr. Springer's classic episodes), Andrew Overtoom, Robertryan Cory, Kenny Pittenger, Casey Alexander, Zeus Cervas, Derek Iversen, Tom Kenny, Dee Bradley Baker, and Luke Brookshier together. Rough Draft Studios also returns to provide animation.
- Fellow former Mickey Mouse (2013) writer/director Clayton Morrow is supervising producer. Dee Bradley Baker and Kevin Michael Richardson have done recurring voice work on that show.
- From Sanjay and Craig , we have writers Casey Alexander, Zeus Cervas, Derek Iversen, Sarah Oleksyk, Johnny Van Ormon, Andrew Overtoom, and Mike Bertino.
- Screwed by the Network: All 13 episodes premiered at 7am over the course of two weeks, receiving little promotion. Reruns would air late at night on the rare occasion they did happen, and the show would be all but forgotten by the network less than a year later, making it the shortest-lived animated series to come out of Disney Television Animation.
- What Could Have Been:
- The Wiki Rule: See here.
- Written by Cast Member: Aaron Springer co-wrote all the episodes.
