Oakland Raiders running back Marshawn Lynch is fierce with a helmet on, but off the field, he’s a gentle Beast.

Lynch announced on Twitter that he will be giving away free tickets to Raging Waters San Jose to the first 2,000 kids who show up.

With the water park giveaway, the Oakland native will be helping families save a good chunk of change. Junior admission passes cost $28.99 a piece.

In order to claim a ticket, people are asked to go to Lynch’s Beast Mode store in Oakland on Saturday from 11 a.m. to 6 p.m.

Lynch is no stranger to giving back. While he was with the Seahawks, he offered free haircuts to kids who pulled in good grades. He also helped former teammate Cliff Avril build a school in Haiti.

He’s the founder and vice president of Fam 1st Family Foundation, created with Giants’ quarterback Joshua Johnson to improve the lives of youth by mentoring them and expressing the importance of education, literacy and self-esteem.
