First of all, the ocean has waves! It’s hard to swim in them. The pool has calm water. It’s much more relaxing.
Next, the ocean is by the beach, and the beach is sandy. The pool doesn’t have any sand. You can swim without getting scratchy sand in your swimsuit. Sand is the worst!
Finally, it’s easier to play games like Marco Polo in the pool. The pool has a big slide too. The ocean doesn’t have that!
