This paper diorama is The Handsome Man and SpongeBob SquarePants, based on the anime SpongeBob SquarePants (SBSP), the papercraft is created by Kamibox. The Handsome Man is an alter ego of Squidward. When Squidward's face got smashed, it was remodeled into a more handsome look. This attracted people, but maybe a little too much, which scared and annoyed him. The face was smashed again back into Squidward's normal face. This event happens in the The Two Faces of Squidward.
There are other papercrafts at the site: "SpongeBob SquarePants – Squidward Tentacles Free Papercraft" and "SpongeBob SquarePants – Squidward Tentacles Ver.2 Free Paper Toy".
The Handsome Man looks just like Squidward, but has a much more handsome face. His chin looks like a real human chin and his cheeks come out of his facial area. Later on The Handsome Man becomes muscular and looks more human looking.
