The story was simple when it comes to write down. A boy found strange creature that seemed to be llost and tried to find tha place where creature should be.
Actually I couldn't find out what the movie wanted to say, but now I think the lost thing is our time or room for enjoying something that is not must for our life. (Hobbies or kind like that)
In the movie boy's parent wouldn't see or think about the creature and were busy to read a news paper or watch the TV. It means I think, they are busy to follow up this changing world. There was no room for playing, enjoying something, or thinking about the thing that isn't necessarily need for our daily life. Too busy.
Sometimes I felt being pressed by time or a lot of things to do and can't have time to calm down.
Many people in this rapidly changing world should have something that makes us feel relax or forget everything. That is the lost thing I think.
