Oh no…this mom thought it was a good idea to sneak a “Mrs. Bigfoot,” into her kid’s 6 year old birthday party. It did not go as planned…

A mother in Oklahoma was hosting a birthday party for her six-year-old girl, and the mom was bummed because her plans for a cake fell through. So she came up with a bizarre back-up plan.

She hired “Mrs. Bigfoot” . . . a.k.a. “Cinnamon” . . . who would be in costume, and would surprise the kids by peeking in the windows at the party.

So Mrs. Bigfoot showed up, and the kids were immediately horrified, and began screaming, running, and crying. Mrs. Bigfoot went in the house . . . and the kids eventually warmed up to her a little, but the mother says the kids still say they never want to see her again.

Mrs. Bigfoot arrived with balloons, wearing a tutu and a bow in her hair . . . so the mom says she thought it would be “cute and fun.” But the kids “did not have that reaction.” (KJRH)

Here’s the video of the kid’s reaction from a local news report:
