My hometown, Oceanside, the Big "O"

This is the main tourist attraction of my hometown,
The picture below of the beach is taken from the pier and shows a sand art image. Can you figure out what it is? It is a lion. I was unable to fgure out what it was but when I finally did, I was so happy!
On the beach, this is Leo's first time ever on a swing. Judging from his smile, you can see he enjoyed it!
