Well, it could be because they want to be part of the warm and cozy world inside. Maybe they're fascinated by the people and the activities. Or it's just a fun and imaginative element the cartoon creators came up with to make the story more interesting.

Maybe he's lost something important outside and is desperately looking for it.
In the story, snowmen can symbolize the magic of Christmas. They are created from the snow, which is a natural element, but during Christmas, they seem to take on a life of their own. They represent the wonder that kids (and adults) feel during this time. They are like frozen friends that bring a smile to people's faces. They also might symbolize the transient nature of the holiday season, as they will eventually melt away, much like the brief but beautiful time of Christmas celebration.
Maybe they had a long day of play or adventure. That could make them look exhausted.
Maybe it's because of certain common design styles or limited creativity in the industry.
Maybe it's because of the way they're drawn - with sharp lines or dark colors that give a creepy effect.
It could be to show that the character is lost in thought or deep in reflection. Sometimes, this expression conveys a sense of shyness or modesty too.
It could be a style choice by the artist to create a unique or dreamlike effect.
