Light would grin and giggle a bit at Shark.
" Nice catch Sweetie, but that's not how you play that game though."
He'd then point to Shark to give back the ball to the players, that is if it's still in one piece.
"There's a lot of sports here to play Shark. It's best that we don't disturb the players from their game and watch them how they play, that way we can decide which ones we wanna join in. And besides, we're still doing some tour in the school. Best we do it another day."
Then Light wondered and asked Bubbles," you got any water sports? She'll be MVP material for sure." He proudly proclaimed.
Meanwhile Light seems to be more interested on his mates happiness rather than to find his sports or hobby or his future in this Equestria.
His only reason for joining was for Shark, since she wanted to learn more about pony kind, and Light wanting to learn more about Shark kind.
"... I wonder what Shark's real parents would think of this situation?... Would they accept me?" Light pondered heavily from his own questions and worry.
