Umm.. is that a snake?

Candace Cameron Bure joined the #TBT conversation on Thursday, May 25 after sharing an alarming throwback family photo on her Instagram account. In the pic, little Candace (or shall we say DJ Tanner?) is posing with a huge snake wrapped around her neck!

"If this isn't an epic #TBT family photo, I don't know what is. #CameronFamily #PetSnakes #NotStyled #RealLife #80s @my3joys @bridgette_r @kirkcameronofficial @barbara162013 and dad Robert," the 41-year-old actress captioned the snap of herself and her brood looking happy as ever.

Just like our first reaction was "OMG!", many of the Full House star's followers commented about the rather strange flashback photo. "PLEASE TELL ME THOSE SNAKES ARE NOT REAL. ?" one user wrote.

Many were quick to point out the resemblance between Candace and her siblings — and some were reminded that Kirk Cameron from Growing Pains is actually her older brother! Candace also has two sisters, Bridgette and Melissa.

"Omg your sister is your twin," a fan wrote. Another followed with, "Oh my God I forgot he's your brother how are you doing? What are you doing now?"

We can't help but wonder if Candace's three kids have pet snakes, too!
