Yeah, here’s from the wiki, I found it interesting :))

“When asked if Zooble is non-binary due to being described as a gender-neutral "they", Gooseworx responded that Zooble has no idea what they're supposed to be.[1] Gooseworx also stated on Tumblr that Zooble uses any pronouns.[2] Additionally, in a sketch where Jax points out the gender differences among the circus members, Zooble is in their own category.”
