Maddie Flour is a weird kid. She talks in a husky, whispering voice and makes those around her uncomfortable with her presence. Whether she does this on purpose or is inept to social cues is not known, but she does try to be friendly with people. She does seem somewhat self aware as she acknowledges that some people think she is evil when really she wants to use her abilities for good.
However, she is also shown to have an edge, being more than willing to curse somebody if pushed enough. This trait was shown in "Cursed!", when she fought Barry when it turned out he cursed Anne and Sprig, and in the online game Locus Pocus, where it was suggested that she will curse Anne and Sprig due to having repaired the bakery. The game also revealed that she actually dislikes working at the bakery.
She is close in age to Sprig and is roughly the same height as him. She is a light blue frog with a lighter underbelly and has a red tongue. Just like the other frogs, she has three fingers and two toes. Her hair is a light pink with dark pink spots and bulbous in appearance with a small knot on her head, making it look like a mushroom cap. It covers one of her eyes, but the one that is visible is big and yellow. She wears very little; just a black sack dress with a rope for a belt and is barefoot.
- Charm casting: Maddie is well versed in casting spells, albeit small ones and can create ones on the fly.
- Baking: Being the daughter of a baker, she herself can bake too.
- It is possible that Maddie has had some unrequited feelings for Sprig prior to the start of the series. Whether or not she still has them since the events of "Cursed!" has yet to be revealed.
