The long story short ... Taker has agreed to personally host the winner of an Omaze fundraising sweepstakes at the WWE Performance Center in Orlando where he will personally customize a RING ENTRANCE for the lucky fan!!
"We're gonna sit down and we're gonna create their own personal ring entrance," Taker tells TMZ Sports ... "So, they're gonna tell me 'Well I wanna do this, I like this, I like this.' So they're gonna get to pick my mind, pick my brain, ya know -- I know a little about entrances!"
"We'll sit there and formulate their own personal WWE ring entrance and then they'll get to do that entrance."
The lucky winner will also stay at a 4-star hotel, meet other WWE superstars and get all sorts of cool WWE merch.
The Undertaker -- real name Mark Calaway -- says he's happy to donate his time and energy since it's to raise money for Make-A-Wish, one of his favorite organizations on the planet.
"When you get to interact with these children and you know what they're going through -- and man, to see the smiles on their faces!? Not to sound cliché but I tell you what, it will put you on point because it makes you realize how blessed you are and it's just a thrill."
"It really has been one of the highlights in my career working with Make-A-Wish."
Taker has done more than 40 Make-A-Wish events over the years -- though he would have happily done more "if it hadn't been for the character."
It's a good point!!
Props to Undertaker -- hope you raise a ton of money!!
