A cute green frog sits peacefully atop a red-spotted mushroom, holding a tiny teacup with both hands. Its oversized glossy eyes, soft blush cheeks, and relaxed posture create a calm, cozy mood. Smooth shading and rounded shapes give the illustration a warm, storybook feel, while the contrast between the bright mushroom and deep black background makes the character stand out. The scene feels whimsical and serene, blending fantasy charm with gentle kawaii style.
