Create a cute, fluffy, grumpy bird with vibrant and textured feathers. She should have a distinct personality shown through expressive, angry eyes and unique posture. Use bright, watercolor-inspired hues like blues, yellows, and greens, and ensure the bird has plump, round body with detailed feathering. Add a small, sharp beaks\ and thin clawed feet for contrast. The bird should be isolated on a solid colored background to highlight the bird's vivid details and fluffy texture. The bird should evoke a humorous, endearing charm while maintaining her grumpy expression.
