Acting for Two: Considering the main cast plays multiple side roles along with their own, this comes up quite a few times. Most notable examples include:
Megan Hilty as Wammawink and Killer Whaletaur.
Kimiko Glenn as Horse and Leaftaur Baby.
Creator's Favorite: Megan Nicole Dong has referred to Wammawink as her favorite character in interviews, with Stabby as a close second. Ironically, Wammawink is The Scrappy to the in-universe birdtaur fanbase.
Creator's Favorite Episode: Megan Nicole Dong's favorite episode changes, but she singles out "Johnny Teatime's Be Best Competition: A Quest for the Sash" as one of the most fun episodes on which she worked.
Descended Creator: Megan Nicole Dong, who is the show's creator, writer, and director among other roles, plays Glendale in the series. She also voices the Tree Shamans on the cast recording and does a few minor voice roles in the show.
Early-Bird Release: The first episode "Hello Rainbow Road" was uploaded to the Netflix Futures YouTube channel four days before the series' official release.
Foiler Footage: It's subtle, but the scene from "Johnny Teatime's Be Best Competition: A Quest For The Sash" used in the season 1 trailer (specifically when Horse starts her performance) has Wammawink in place of Splendib watching it unfold.
In Memoriam: "My Tummy, Your Hurts" is dedicated to Maryam Chin Graul.
Kimiko Glenn is usually cast in animation as cute Genki Girl characters. Her character Horse is almost the complete opposite of her usual work, being a tough, angsty and melancholic sane woman to the quirky centaurs.
The series was meant to be a single season with 20 episodes total, but was instead cut into two seasons with the first having 10 and the second having 8, with the last three episodes being merged into one seventy-minute finale special.
Originally, when Gebbrey was inside of Glendale's portal tummy in Season 2, there was a scene where he came across her parents while they were watching TV/living within the portal tummy. It ended up being cut out of the final product.
On his way to becoming the Nowhere King, the Elk would have been shown becoming the leader of a large cult comprised of humans, animals, and other creatures, all of whom he would have used in creating the first minotaurs.
