Small notes, Pierrot isn't french for "clown" (it's still clown, but pronounced differently, kinda like a mix between "cloud" and "clone") but Pierrot is a type of clown

Somewhat surprised they're trying to do in live action, it's a fan favourite but that's going to be pretty hard to do between the acrobatic and the general weirdness of it.
I'm guessing they're not introducing Ed but will if it get renewed for a second season. I guess no Ed means no mushroom episode...
