(1) the Story and the Relationship
In the beginning, a huge monster appears exaggeratedly in the whole screen, and then it(the monster) starts reaching a small house quite gradually. A little and ball shaped monster (I guess I can call him Clod)just gets up from sleeping, comes out of his house and finds such a big problem in front of him that he himself cries out loud (or he means it's trying to break my house...and probably kill me). He attempts to move his house, which is too heavy for him to transfer. Seeing the monster, Clod then runs to him on purpose to push it back far away. Both of these ways just fails, and he falls down on the floor. The monster brings him up to its mouth and swallows him after a while. He goes down fast into its stomach and settles at the bottom. In its stomach, there is nothing for the large space. Before the little boy monster notices something coming down to him, his small house has already covered all his body. This means his house is back with him. It seems that he is so lucky that he even feels attachment to his lovely home. But suddenly their happy time comes to an end because they're thrown out to the ordinary world again; there is a long line of the huge monsters (they're all dragging their feet(?) and approaching the protagonist of this story) each of which looks the same and even their walking pace never changes the speed. Clod shouts again. Then the sight of the film recedes into the distance.

The content and setting were difficult to understand. The reason for this I suppose is that this film is just an animation for the audience like children to enjoy how the characters act and behave. But it could be that the symbol of this movie is "bad lucks are always waiting for everyone", I guess. Observing the last scene, I realized that something like social problems and other kind of troubles never fail to happen, and they rather go on emerging in front of people in any way. We cannot avoid our bad fate and we may deserve having the duty to solve those kind of problems at last.
