The turtle refused to go back in its shell.

Vikings safety Andrew Sendejo, however, did leave his comfort zone for an exhilarating moment while dressed in a Raphael costume from Teenage Mutant Ninja Turtles.

The eccentric Sendejo, who excelled in martial arts during his youth, participated earlier this month in the annual "**Over the Edge**" fundraiser to benefit Make-A-Wish Central & South Texas.

Participants who raised or donated enough money were allowed to rappel and lower themselves 38 stories down a skyscraper hotel in Austin, Texas, to help grant wishes to brighten the lives of young people who are battling life-threatening conditions.

Sendejo had seen the event last year and committed to participating this year. He said it was an interesting way to help the young people.

"You get to kind of challenge yourself to face something that's pretty scary, to lean off the edge of a building at 40 stories high, but at the same time, you're helping someone else out, so it's like a two-for-one special," Sendejo said. "You're kind of overcoming something for yourself and helping someone else in need to try to help them overcome something that they're going through, too."

As much as the adventurer looked forward to the unique experience, the first look down was a doozy.

"The first thing you do is put the balls of your feet on the edge, and your heels are off," Sendejo recalled. "They didn't tell me if I fell over I would be secure, so I was still holding on. They said you're good to go, and the first thing you do is lean back so you're parallel to the ground, and they make you take both your hands off. The scariest thing you can possibly do is be up top with no hands.

"After that, it's very easy," Sendejo added. "They had a lever that you could pull on to let the rope through and you just go all the way down. I would take an occasional break and look around, enjoy the view, so it was cool."

Sendejo greeted the young people in attendance who are helped by Make-A-Wish and said he might try to put together a team to raise more money for the cause next year.
