A 1930s cartoon-style water bottle character standing on a beach under the hot sun. The bottle is half-empty, with a transparent glass-like body showing sloshing water inside. It has large pie-cut eyes, a cute rubber hose mouth sticking its tongue out tiredly, and simple black rubber hose limbs — thin, bendy lines for arms and legs, ending in mitten-style hands and sock-like feet. It looks adorably exhausted, slightly slouched, with wavy heat lines around its head. Drops of sweat and steam rise from the cap. The beach is stylized like a 1930s cartoon set: simple palm trees, bouncy waves, and soft sand, all hand-drawn with watercolor texture. The whole scene has vintage film grain, flickering reel effect, and a warm, sepia-toned pastel palette. Very cute and old-school charming.
