Create a digital illustration of Pikachu enjoying a relaxing day at the beach. Pikachu is lying on a beach towel, wearing sunglasses, and sipping a tropical drink with a tiny umbrella in it. The sun is shining, and the ocean waves are gently lapping at the shore. In the background, you can see palm trees swaying in the breeze and seagulls flying overhead. Make sure to include plenty of bright colors and playful details to capture the cheerful and fun-loving spirit of Pikachu.
