Art style: 3D Pixar.
Pixar-style 3D animation. A funny baby brontosaurus is in one of the train wagons, struggling to hold a giant, wobbly birthday cake. The train bounces on the tracks, causing the dinosaur to look comically worried. The scene is filled with bright colors and a playful mood.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "3D Pixar" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "3D Pixar".
Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "3D Pixar" idiom, not in any other medium.
Character appearance reference (MUST match exactly):
- Cake Brontosaurus: A tall baby brontosaurus with a long, graceful neck. He has large, innocent brown eyes and a goofy grin. He's often seen carefully balancing a giant birthday cake. His skin is a sunny pastel yellow.
