Mrs. Flibbertigibbet

Mrs. Flibbertigibbet first appeared in the Season 2 episode "Bright Ideas". 
She came into the shop looking for an idea, because it seems to her that everytime she had an idea someone else had already come up with it, like her safety pin idea. Mopatop thought that what she needed was a bright idea, but unfortunately the shop had run out of bright ideas, so instead they gave her some bright things. Then a mole entered the shop and all of a sudden she came up with three ideas based on the bright items she had gotten from the shop.
