A vibrant cartoon with colours and smooth animation. Create a 30-second cute 3D cartoon for toddlers. Nubu is a cute baby brown bear in a colorful garden. Nubu says: "Hello friends! I'm Nubu! Look! What color is this? Red! And this one? Blue! Wow! Yellow! Let's say them together: Red, Blue, Yellow! Bye-bye, friends! See you soon!" Use a cute child-friendly voice, cheerful music, bright colorful animation, and simple toddler-friendly visuals. Keep Nubu's appearance consistent.
