Create a playful and lively image featuring a cheerful frog sitting on a floatin

Create a playful and lively image featuring a cheerful frog sitting on a floating piece of oak wood in the middle of a gently flowing river. The frog should be mid-hop, with one leg extended as it prepares to jump, while the other leg rests on the oak. The frog should have a joyful expression, with its mouth open as if it's croaking. The surrounding river should have ripples, with the reflection of the trees and sky in the water. The background could include lush green riverbanks with tall grasses, flowers, and maybe a few other critters like dragonflies or fish to add life to the scene. The atmosphere should be bright and sunny, capturing the fun and whimsy of the moment.
