What the picture shows

A pixel-art green bird character with an orange beak is shown from behind, wearing bright blue pants with a prominent seam down the center of its rear, and the image appears to be a frame from a shaking animation. Chatters would likely use this to express a silly, cheeky, or exaggerated reaction, often for comedic emphasis or when something is shaking or twerking.
