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 cake is festive and brightly decorated, but any number, ages or names. 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.
