As an animation fan, I enjoy shows with cute animals. I like various types of animals, and raccoons are certainly one of them.
The series centers on Carl, an anthropomorphic raccoon, who, as the show's title implies, likes collecting stuff. Besides collecting stuff, Carl would at times use his collections to solve problems, and help others.
Things that bring up the score for this show are the cute characters. The fact that Carl is autistic makes him a more interesting character. Those on the spectrum may show great knowledge in some fields, but struggle in others. In Carl's case, he knows a lot about the things he collects, but tends to get in shock when he sees someone have an accident he never saw before. Nevertheless, his friends are willing to help him in some challenges.
What can I say of this series? Well, when it comes to collecting things, and using them in situations, I see it as a clever concept.
