Where is the fantasy space robot haunted by bears?

Coco (Little Iron Robot), the character of the animated film "Bear in Fantasy Space", was originally an intelligent treasure-hunting robot invented by an archaeology professor, and went to look for golden antlers with Xiong Er, Logger Vick and Nuna Ya. Finally, he sacrificed himself to save the forest in Neverland, and was brought up by Hericium erinaceus elves. It shows the friendship between humans and robots. The little iron in the animation is a treasure-hunting machine that is too talkative.
