Cartoon Character Round Oversized Head Expressive

Create a cartoon character featuring a round, oversized head with large, expressive eyes and a wide smile. The character should have a bright green skin tone and small pink blush on its cheeks. Change the outfit to a colorful, patterned vest with a bow tie instead of stripes. The character's hands should be animated, giving a playful thumbs-up. Add small, quirky details like a few freckles on the cheeks and a playful wink in one eye.
