Matt Stanley and Andrew Flounder were hitting the waves in Amble, Northumberland, when the friendly seal attempted to join in with their fun.
Andrew first noticed something was fishy when he felt something nudging his foot but, luckily, it was just the adventurous animal wanting to make friends.
Matt explained: "The look on his face was classic. He got such a fright because he didn't know what it was. Once we realised it was a seal, we relaxed a bit."
But instead of swimming away, the youngster decided to jump aboard and catch some waves with his new mates. And the trio even captured the moment with the ultimate selfie.
It seems like these three had a flipping good time together!
