This is an Amazon Prime series and as far as I know, you can only get it if you have that. In fact, right now, there's only a pilot, released in February of last year. Not sure when or if they'll make more. Anyway, the sneeze is from the main character Bianca's teddy bear, Bob, at approximately 4:30, caused by "magic glitter."
