A table is a big rectangle with long and skinny rectangles. A bird is made of circle for its head, triangle for its beak, and rectangles for its body and tail. A Pikachu-

In the Poke-world, the most fantastic and illustrious physiques of Pokemon could be broken down into basic shapes. Some are gifted with immortality, meaning their physiques never diminish as their peers, acquaintances, and humans slowly disappear. People long and root for positivity and comfort, or beings that convey this.
