Fake cast list? ("Adventures in Wonder Park")

https://www.imdb.com/title/tt7714560/?ref_=ra_gb_ln

On Stephen Tobolowsky's podcast, he elicited surprise that he was somehow cast on the animated series "Adventures in Wonder Park." I'm assuming that this information about Tobolowsky being on this show is false. I tried to delete it but I am unable to, so I am leaving it in the admins' hands. Maybe the entire cast list should be fact-checked; I don't know.

BTW, here's the link to the podcast in question. At the very beginning of episode 89.
