The world of Paper Mario the Origami King is beautiful and meticulous. When playing Paper Mario, you are aware of the paper environment, but as a whole, the world can be quite absurd. The Paper Mario moves alongside a 3D world. The story follows the same plot that Mario engages in, such as rescuing Princess Peach.

Mario and Luigi have to save Princess Peach, who has become brainwashed and turned into the mural as King Olly wants to create the Origami Kingdom. It all started when the Origami Craftsman wrote on his paper disrespecting origami.

In Paper Mario, the castle itself is moved to a volcano. Mario and his friends face obstacles such as Colored Pencils and Water Velumental. They also find themselves in various peculiar places such as Sandpaper Desert. There are also unparalleled events, such as the disappearance of the sun or the spa placed in the clouds.

Mario and his team have to ensure that all things change back to their original form, so they need to restore the sun, defeat all unusual obstacles, including Tape, Scissors, Pokey in the dessert, or Stapler. They also need to hunt Toads. Peach also needs to regain her previous appearance after being turned into a mural.

Before Paper Mario joins the battle, various puzzles need to be solved. Some companions can help to solve these puzzles. While Mario is searching the desert, his friend Professor Toad helps hi to find hidden treasures. The battles are played on a ring, where Mario attacks from the center his enemies, throwing them out. They fall across and attack again. He has a certain number of moves.
