Jane's real name is Joy.
Her true form is a clown!
As a clown, she has milk white skin, a rainbow afro, a round, red nose the size of a cherry, long eyelashes, blue around her eyes, pink hearts on her cheeks with black freckles, ears twice as big, plump red lips, a large gap between her buck teeth, size 25 feet, and an exaggerated hourglass body.
Her 17-year-old daughter thinks clowns are annoying, her 10-year-old son is scared of them, and her 5-year-old daughter thinks they're cool.
She's done her best to convince her son that clowns aren't scary, and that they only want to make people laugh, but he's still afraid of them.
Jane (or Joy) does this not only because she's secretly a clown herself, but she knows that all four of her kids would become clowns sooner or later.
She wears her human suit - a combo of magic and science - that hides her true form, as well as her helium voice, which has a lisp due to her teeth.
Tonight, her disguise was off, and while everyone else was asleep, she was quietly sining her baby girl to sleep.
What she didn't realize was that her lisped helium lullaby had caught some one's attention, and they saw her!
