I think this is a very touching cartoon! At the beginning, the hero loved his wife very much (a good partner who grew up with him and cherished his dreams together, which can be said to be childhood friends). His wife drew a picture and built a cabin next to a big waterfall. They can live happily there, and they both yearn for that kind of paradise. Later, his wife was gone, and he stayed alone in the cabin and missed her very much. Later, it was going to be demolished. He decided to keep the cabin, so he got a lot of balloons and took the cabin to find the fairyland. Russell and Ronaldinho started this journey together unintentionally. The protagonists Carl and Ronaldinho both had persistent hearts for a moment, one for a dream place to find and the other for a badge. At first, Carl was fed up with Ronaldinho. All he could think about was the waterfall. He was indifferent to the little guy and was not very interested in what was happening around him. But Ronaldinho was full of dreams and curiosity about the world, and he met a rare big bird. Later, the plot was deeply touched. The big bird was taken away by the bad guys. Ronaldinho could not resist Carl's opposition and went to the bird alone. This is Carl looking at Ronaldinho, thinking that he can't fight the bad guys at all, so he pushed out the sofa and small table made with his beloved in the hut and let the house fly again to help Ronaldinho. He didn't feel it, but he just thought that dangerous children might appear at any time. After fierce fighting, they won, but Carl's cabin fell off the big airship. At this time, Carl looked at it and felt very sad. But what he said at this time made me think for a long time and said deeply: It was just a house, and finally they became good friends in trouble.
