Kappa Banana Day Anime Poster

Create a cheerful vertical anime poster celebrating {argument name="holiday title" default="かっぱちゃんのバナナの日"} with the date text {argument name="date text" default="8月7日"} prominently displayed at the top. The scene shows a cute young anime girl named {argument name="character name" default="かっぱ"} standing centered, smiling brightly and waving with her right hand while holding one bunch of bananas in her left hand. She has short dark teal bobbed hair, large golden-brown eyes, rosy cheeks, and a happy open-mouth expression. Dress her in a translucent pale green kappa-themed raincoat with dark teal trim, oversized buttons, two front pockets, and a small white name tag reading {argument name="name tag text" default="かっぱ"}. The hood is up and shaped like a playful kappa face, with big cartoon eyes, a yellow duck-like beak, and a dark teal bow or leaf-like crest on top. Add bright yellow rubber gloves and matching yellow rain boots with dark teal soles and button accents; pose her with one leg slightly lifted for a lively childlike stance. Use a soft pastel cream-yellow background with mint-green ground at the bottom, rounded clouds, sparkles, tiny hearts, blue raindrops, and banana motifs. At the top, place a curved cream banner behind the headline, with rounded orange-yellow Japanese lettering and small banana decorations. Include exactly 11 visible banana elements: 1 bunch in her left hand, 1 large banana bunch at upper left, 1 single banana at upper right beside the date, 1 peeled banana at left middle, 1 small curved banana icon at right middle, 1 peeled banana at right lower middle, 1 single banana at lower left, 1 large bunch on the bottom left ground, 2 sliced banana coin pieces near the bottom left, and 1 large bunch with several slices on the bottom right ground. Use a polished watercolor-anime illustration style, soft linework, warm lighting, glossy raincoat transparency, cute mascot energy, clean poster composition, and no extra text or watermark.
