The story is about a group of friends visiting a girl’s room, where they meet her cat Atomic and see her books, pencils, and desk. During their visit, she shows them her new project – a computer that she is building.
While they are talking and playing, the cat causes a big mess — books and papers are everywhere, and the girl’s pen goes missing under the desk. After they find it, everyone decides to clean up and organize the room.
In the end, they discover that the computer project is finished successfully, and everyone is impressed. They even praise Atomic for helping in his own funny way.
