The beach was the only place available for anyone to relax, as half of the entire town went there to relax in the sun, build objects made out of sand, or even swim in the water whether they do, or don't have a surfboard. One more thing that people like to do is eat ice cream, which was exactly what the Magic Shop was selling.
When on the beach, the manager of the Magic Shop has hired some female employees to sell ice cream all over town, and the ice cream being sold at the beach was from a cart. With the purple umbrella hanging from the white ice cream carts, beach goers will notice women wearing black one-piece swimsuits, along with purple towels wrapped around their wastes, and matching visor caps as uniforms. Luckily, as you were relaxing on the beach, you noticed the cart coming towards you.
