Alabama girl waves her new prosthetic arm in welcome home parade after losing two limbs in shark attack while at beach

The Alabama teenager who lost a hand and a leg in a Florida shark attack has finally returned home - showing off her new prosthetics to a parade of supporters.

Lulu Gribbin, 15, was swimming on a mother-daughter trip to Walton Beach on June 7 when she was mauled by a shark.

The shark had bitten off Gribbin's left hand and doctors had to amputate her right leg halfway up from her knee to her hip. Her friend McCray Faust, 17, also suffered injuries to her foot.

After 11 weeks staying at Sacred Heart Hospital in Pensacola and at Levine Children's Hospital in Charlotte, North Carolina, the teen finally returned home to Mountain Brook, Alabama on Friday.

Gribbin was welcomed with a parade of people decked out in purple - her favorite color - and rode on the back of a golf cart where she waved at the crowds with her prosthetic arm.

The teen documented her recovery on Instagram and showed she has maintained a sense of humor by wearing a shirt that says, 'Before you ask, it was a shark'

'We are incredibly thankful to have our family back under one roof for the first time in 77 days. We look forward to our family’s next chapter and seeing everything that Lulu will accomplish,' her mother Ann Blair Gribbin said in a CaringBridge update.

Supporters attending the parade said they showed up to show Gribbin how strong and how much of an inspiration she is.

 'I was just thinking how much of an inspiration she is that she keeps going because I don't know if I could do it what she has done,' seventh grader Kennedy Romeo told WVTM. 'Her recovery was amazing to watch.'

'I'm here to support her,' Leslie Higgins said. 'She's a very strong individual and if that were me, I would have been freaking out. I want to tell her, "you're a strong individual, you're a strong woman. Keep going."'

The teen has documented her recovery on Instagram, sharing photos and videos as she learns to live with her new prosthetics.

Gribbin's tried out adaptive sports such as basketball, soccer and riding a bicycle. She even got to attend an NFL preseason game between the Jets and Panthers as a physician led therapeutic outing.

The teen's brutal attack occurred around 3 p.m. that fateful day when Gribbin's and her friends were swimming near a sandbar.

A crowd formed around the edge of the ocean, which had been evacuated by Walton County authorities and lifeguards. That's when Gribbin's twin sister Ellie came up their mother and told her Gribbin's had been attacked.

'I saw her wounds on her leg and started to scream. She was lifeless her eyes closed mouth white and pale. The wound on her leg or all that was left of her leg was something out of a movie,' the mother said.

Two men were able to get Gribbin's out of the water and several medical professionals on the beach ran up to help.

She was then airlifted to a trauma center in Pensacola in critical condition.

Just four miles away on the same day, a 45-year-old Virginia woman, Elisabeth Foley, was bitten by a shark at around 1:15pm. 

She suffered significant injuries to her abdominal and pelvic region, with the lower part of one of her arms having to get amputated.

Alabama Sen. Katie Britt has proposed legislation called Lulu's Law in honor of the teen that would authorize phone emergency alerts about shark attacks.
