Q 版鲨鱼冒险电影海报

A bright, hyper-energetic Japanese movie poster illustration in a polished anime chibi style, set in a sparkling tropical ocean adventure scene. Center the composition on 2 cute chibi children riding a smiling blue shark that leaps diagonally upward through swirling seawater and white splash effects. The left child is a boy with short black hair, huge glossy blue eyes, a happy open-mouth smile, a black T-shirt, dark shorts, white sneakers, and a light blue shark hoodie with a tooth-edged hood framing his face; he points upward with one hand and hugs the shark with the other. The right child is a girl with orange hair, large glossy purple eyes, a joyful open-mouth smile, an orange dress, pink shoes, and a pink shark hoodie with a tooth-edged hood; she throws one arm wide in excitement while holding on with the other. Make the shark large and friendly with a rounded body, pale belly, tiny black eyes, and a wide open mouth. Surround them with a vivid underwater-and-surface world: schools of small tropical fish, exactly 1 sea turtle on the left, exactly 1 dolphin on the right, exactly 1 pink octopus on the right, exactly 1 pufferfish on the lower left, coral reefs and sea plants along the bottom edges, air bubbles throughout, and strong blue water motion lines. In the upper background, show a sunny sky with dramatic sun rays streaming into the water, fluffy clouds, 2 seagulls flying, a rocky tropical island with palm trees on the upper left, and a pirate ship on the upper right with white sails and a cute shark emblem. Add a ship wheel partly visible behind the main title. Use a dense, exciting Japanese kids-anime promotional layout with oversized 3D lettering and explosive effects. At the top, place the giant Japanese title text {argument name="headline text" default="サメなの ワクワク 大作戦"} in stacked lines, with glossy blue, orange-pink, and yellow-orange gradient letters, thick white outlines, dark blue shadows, water splashes, and sparkles. Beneath the title, add a smaller curved Japanese tagline in white with blue outline: {argument name="tagline" default="さあ、海のむこうへ！最高の冒険がはじまる！"}. At the bottom, place huge release text in Japanese, {argument name="release text" default="2026年 夏公開"}, in bold red-to-yellow gradient 3D letters with white and blue edging, sitting over a radiant orange burst. On the lower right, add a blue starburst badge with the Japanese text {argument name="badge text" default="ドキドキ！ワクワク！いっしょに出発だ！"} in white and yellow. Include exactly 2 treasure-themed corner props: an open treasure chest with gold coins at the lower left and a compass at the lower right. The overall look should be glossy, saturated, family-friendly, whimsical, cinematic, and toy-like, with crisp outlines, exaggerated expressions, high contrast, and a poster-ready vertical composition. No photorealism, no muted colors, no minimalism.
