Snowman Operation

This is a Pixar animated short film with a cute little snowman. The beautiful decorative bottle is the home of the little snowman, of course the kind with snowflakes floating on it. The little snowman couldn't help but fall in love with the tropical mermaid who was also a toy, but his beloved did not live in a bottle, she was in the wider world outside. For the little mermaid and for love, the little snowman launched a series of escape plans. Screwdrivers, electric setters, and even bombs were used one after another, but apart from making the house snowy, the little snowman made no progress. In an explosion, the decorative bottle was knocked off and fell. During the fall, the little snowman finally saw the "safe exit" of the bottle, and he opened the door excitedly. This time he was finally very close to the mermaid, but where was he? Why is happiness always visible but not tangible?
