Fast, playful montage composition: the robin hopping from a rail to a tree branch to a garden wall to a spade stuck in the soil, the cat chasing in each mini-panel, all linked by swirling musical notes, bright daylight, energetic action, comic-book rhythm in a 3D cartoon style, dynamic diagonal framing. Little Robin: Small European robin, plush 3D cartoon proportions, rounded head, glossy black eyes, soft brown wings, bright orange-red chest, cream belly, tiny feet. Expression style: curious, cheerful, nimble, slightly theatrical head tilts. Recurring pose language: perched on rail, hop-flying, chest puffed proudly, wings half-open. Cat: Fluffy gray tabby, yellow eyes, pink nose, playful but harmless, rounded 3D form. Expression style: mischievous, surprised, playful chase energy.
