She would be threatening to turn Big Bird into a feather duster, David into a basketball and make it rain in Hopper's store though.
That kinda makes me think of her entrance in this episode: so she's flying and loses the broom... wouldn't she go plummeting into the pavement, lol? I wonder what exactly (if anything) they showed of that.
I kinda looked back at the episode guide (which was a godsend btw), and you can really visualize what this episode looked like, and it might actually turn out being underwhelming tbh; like I still want to see it, but it doesn't really seem like much and happens, and nothing could honestly live up to the lore and aura of this episode.
