While Dwayne "The Rock" Johnson was eating lunch with Ashley Rodriquez and Larry Orozco-Chavez, whose wish was to meet the actor, Efron made his way over to his Baywatch costar to join in on the fun.
"Zac was so genuine and interested in both of the kids," an onlooker told PEOPLE.
Efron, 28, took to Instagram to share a few snapshots from the afternoon, writing that he bonded with Rodriguez and Orozco-Chavez over basketball and heart signs.
"Thanks to the @makeawishga and @therock for giving me the chance to hang with my new friends- Ashley Rodriguez- the cutie who taught me to hold up the heart sign- and Larry Orozco-Chavez - who loves #Fifa and @KobeBryant even more than I do," he captioned the photo. "#Baywatch is brighter now"
Johnson, 43, also posted a slew of photos to his Instagram account, writing that the day was full of both laughter and tears.
I mean there's cool dudes, and then there's COOL dudes. My buddy Larry Orozco-Chavez from Make-A-Wish is THAT cool dude. Such a pleasure getting to hang with him and his family today. We chopped up talkin' about video games (he's a hard core gamer), my WWE matches, movies, took selfies, shot videos on our phones of each other and his mom even asked me to bounce my pecs up and down! I mean don't threaten me with a good time, so I was pec poppin' all over the place much to the amusement of Larry's mama and much to the embarrassment of Larry himself. When I sat down with Larry, he said something to me that struck a chord. He said, "Dwayne Johnson (he often called me by my full name today which was awesome) when you walked in today my heart was beating so fast I didn't know what to do. Then you started talking to me and it slowed down and everything was good". I shared with him that that happens to me sometimes. I get so worked up before something big happens (shooting an intense scene, performing in front of 100,000 people at WrestleMania) that my heart feels like it's beating out of my chest, BUT the moment I realize "I got this" then all the angst goes away and I'm ready. So next time something like that happens with him, I told just remember "you got this", be calm, cool and you'll be ready. Made me think of everything this kid has been thru up to now - making him more stronger than many of us could ever imagine. We wrapped up our visit, I gave him a lil' gift and said our goodbyes. It was a real pleasure kickin' with you today, Larry. I can't begin to tell you what it means to me. Just know how grateful I am to share your time, your laughs and definitely grateful to have been able to pop my pecs for your family. Stay cool and remember... you always "got this". #OnSet #Baywatch #MakeAWish #LarryOrozcoChavez #AndOneVeryLuckyBigBrownBaldDude
A very special day. Today, I had the pleasure of meeting and spending time with Ms. Ashley Rodriguez from Make-A-Wish. I walked in, walked right over to her and... she started crying, then her mama started crying (in the background), then dammit I almost cried, but everyone was watching so I held it together 'cause I'm tough as nails. We hung out, ate some lunch together and chatted about all the cool things we have in common - our love for pizza, our fear of spiders (don't tell anyone Rock's afraid of spiders;) and our love for our dogs. As a matter of fact Ashely loves animals so much that she wants to be a veterinarian one day which is awesome - she'd make an amazing vet! Took lots of selfies, laughed a ton, gave her a few gifts and then we wrapped up our visit. Ashley, you made my heart full today and I'm such a lucky guy to have been able to spend time with you. You stay strong, stay awesome, keep smilin', enjoy the gift and always keep lovin' pepperoni pizza. And I'll do the same! Lastly, I want to thank everyone who made Ashley's and her family's trip possible. So many people who I don't even know, but please know that I'm grateful from afar. Always say this, because it's true.. this is by far the best part of my fame. #Onset #Baywatch #MakeAWish #AshleyRodriguez #AndOneVeryLuckyBigBrownBaldDude
Rodriguez even managed to steal a kiss from the actor before leaving.
While the kids' wish was to meet Johnson, a rep at Make-A-Wish said they were not surprised that Efron decided to stop by.
"Zac has been an avid wish-granter and supporter of Make-A-Wish," the rep told PEOPLE. "He has granted both wishes to meet him as well as made several through High School Musical and other movie premiers and set visits."
Efron's generous effort comes after his sudden split from Miró, in which he deleted all photos of his ex from his social media accounts.
"A month ago he was talking about how he missed her when he was away shooting Baywatch," a source tells PEOPLE of Efron, who, the source adds, would come home on weekends to see Miró.
On Tuesday, Miró was spotted out with DJ Alex Andre in West Hollywood, and a source confirms to PEOPLE that the two are dating.
