Whimsical Cartoon Frog with Wizard Hat

Cute whimsical cartoon frog illustrated in a hand-drawn ink style, standing upright and casually walking on two legs, relaxed posture, slightly grumpy but calm facial expression, wearing a simple slightly oversized pointed wizard-style hat, holding a takeaway coffee cup with lid in one hand while walking, no scooter, natural smooth step motion, soft muted green frog body with subtle line shading and visible small texture details, clean black outline with vintage illustration feel, minimal simple composition with no additional objects, flat vector-style artwork with crisp edges, isolated on a solid teal background, no shirt, no fabric texture, no text
