Spongebob and Patrick are walking along the beach, their hands full with jellyfish nets, glittering in the sunlight. Squdward is standing in the sand near a sandcastle, also with a jellyfish net in his hand. A long, crusty trail of jellyfish leads all the way up to where Sandy is sitting in a jellyfish chair, nose deep in a good book. For this image, I would recommend coloring the characters in bright, festive shades, and giving the jellyfish in the nets and on the beach a gentle aquamarine hue. The sandcastle can be painted with a sandy yellow to bring out the detail, and Sandy's chair should be shaded a vibrant purple. Add a few tendrils of cheerful blues and pinks in the sky and sea and voila, you have a wonderfully vivid illustration!
