Goal: Create a cute LINE-style animated

Goal: Create a cute LINE-style animated sticker sprite sheet featuring a single mascot character, orange jellyfish mascot, with the appearance of a soft peach-orange jellyfish wearing a small cream seashell flower accessory on the upper left side of its bell. The character has glossy watercolor shading, rosy cheeks, rounded black eyes, a tiny smiling or expressive mouth, wavy tentacles, and clean dark reddish-brown outlines.

Canvas: Square 1:1 image, about 1254×1254 px, arranged as a clean 4×4 sticker sheet on a light gray-and-white checkerboard background that looks like transparency. Leave even spacing between stickers and keep every sticker fully visible with no cropping.

Layout: Use exactly 16 discrete sticker frames in a 4 columns × 4 rows grid. Each frame contains one jellyfish pose plus one white speech bubble with a dark reddish-brown outline and bold rounded Japanese text. Speech bubbles sit above each character, with a small tail pointing toward the jellyfish. Use orange motion marks, bubbles, and small emphasis lines where appropriate.

Sticker count and labels: Row 1 has 4 morning greeting stickers labeled 「おはよう!」: 1) front-facing happy jellyfish waving one tentacle, 2) smiling with closed crescent eyes and one long raised waving tentacle, 3) front-facing happy wave with small motion arcs, 4) rear/side view waving with the face partly turned away. Row 2 has 4 thank-you stickers labeled 「ありがとう!」: 5) shy bowing jellyfish with closed eyes and tentacles gathered, 6) straight-on deep bow with closed eyes, 7) small bowing pose with body lowered and side motion marks, 8) side-leaning bow with tentacles trailing to the right. Row 3 has 4 surprised stickers labeled 「びっくり!」: 9) front-facing wide-eyed shocked expression with small round mouth and orange exclamation mark, 10) similar front shocked pose with two emphasis marks, 11) smaller jellyfish startled upward with vertical speed lines beneath, 12) rear/side startled jump with bubbles and vertical motion lines. Row 4 has 4 tired stickers labeled 「おつかれさま」: 13) sleepy yawning jellyfish rubbing or holding a tentacle near the mouth, 14) larger yawning pose with closed eyes and drooping tentacles, 15) exhausted front pose with half-lidded eyes, small frown, and bubbles beside the head, 16) sleepy side-lying or drifting pose with closed eyes and open yawning mouth.

Visual style: Kawaii Japanese sticker illustration, soft watercolor texture, warm coral-orange body, pale cream frilled rim, translucent tentacles, subtle highlights and blush, rounded shapes, polished digital art suitable for messaging stickers. Use consistent character design across all 16 frames.

Text content: Preserve the visible Japanese text exactly as shown: おはよう!, ありがとう!, びっくり!, and おつかれさま. The lettering should be thick, hand-drawn, rounded, dark brown, centered inside each bubble.

Constraints: Exactly 16 stickers, exactly 4 columns and 4 rows, no extra characters, no watermark, no English text, no frame borders around individual stickers, keep the checkerboard background visible across the whole canvas as if it were transparent.
