Simple 3D animation for kids

I need a simple 3D animation in the style of a "run/race" video, similar to the example I'll attach. The video features two characters moving along a track, interacting with objects (choosing between two options — "kiss or save"), with simple physics-based falls/reactions. The style should be bright, cartoonish, and easy for a child audience to enjoy. What I need: A short animated video (15–60 seconds) in a similar style Simple 3D character models (stock/ready-made assets are fine — no need for a complex custom model) Smooth movement along the track, basic walk/run animation and reactions Vertical format (9:16) Final render in mp4 Style reference: I'm attaching a reference video for guidance on dynamics, camera angle, and type of content.
