Chibi Shark Ocean Adventure Anime Poster

A bright, hyper-energetic Japanese movie poster illustration in a polished anime chibi style, set in a sparkling tropical ocean adventure scene. Vertical poster composition centered on 2 cute chibi children riding a smiling, friendly blue shark with a rounded body, pale belly, and open mouth, leaping diagonally upward through swirling seawater and white splash effects. The left child is a boy with short black hair, glossy blue eyes, a joyful smile, a black T-shirt, dark shorts, white sneakers, and a light blue shark hoodie with a tooth-edged rim, pointing up with one hand while hugging the shark with the other. The right child is a girl with orange hair, glossy purple eyes, a cheerful smile, an orange dress, pink shoes, and a pink shark hoodie with a tooth-edged rim, flinging one arm wide in excitement. Surrounding them in a vibrant aquatic world are 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, colorful coral reefs along the bottom edges, rising bubbles, and dynamic blue speedlines. In the upper background, a sunny sky with sunbeams piercing the water, fluffy clouds, 2 flying seagulls, a rocky tropical island with palm trees on the upper left, and a pirate ship on the upper right with white sails displaying a shark emblem, with a wooden ship wheel partially visible behind the title text. At the top, giant 3D Japanese title lettering in stacked lines with glossy blue, orange-pink, and yellow gradients, thick white outlines, and water splashes: "[サメなの ワクワク 大作戦]". Beneath it, a smaller curved Japanese tagline in white with blue outline: "[さあ、海のむこうへ！最高の冒険がはじまる！]". At the bottom, huge release text in bold red-to-yellow gradient 3D lettering over an orange burst: "[2026年 夏公開]". On the lower right, a blue starburst badge containing white and yellow text: "[ドキドキ！ワクワク！いっしょに出発だ！]". Corner accents include an open treasure chest overflowing with gold coins at the lower left and an antique compass at the lower right. High contrast, saturated colors, glossy toy-like aesthetic, crisp outlines, no photorealism, no muted colors.
