A 12-year-old girl was booted from a Wisconsin school for allegedly selling sex toys – which her family insisted are innocent “water snake wigglies” used to help autistic kids.

Frances Habeck said she received permission to sell the water-filled bags for $1 between classes at Trinity Lutheran School in Racine, according to WTMJ-TV.

But on Feb. 9, she was yanked out of her basketball game and accused by principal Pamela Amling of selling X-rated toys.

Frances was suspended for three days.

“I started crying,” the girl recalled.

Her father, Milt Habeck, was outraged over the unfair treatment of his daughter.

“It’s nuts because she’s an adult,” he said about Amling. “She should know better. She should know that this has nothing to do with sex.”

He said the slippery toys, also used as stress relievers, in no way resemble lewd objects.

“In your wildest imaginations, no adult could possibly view this as a sex toy. This is a water-filled bag,” the dad insisted.

Pastor David Gehne said the school board took up the issue – and sided with the principal’s actions.

“We wouldn’t discuss the details of any situation regarding one of our children. They’re all minors,” said Gehne.

But now Milt is fighting to have his daughter’s name cleared.

“The spirituality of that place is busted,” the dad said. “Something’s got to change there. And we’re powerless to do it.”
