It seemed like the Pikmin series' core gameplay was already well-defined, but Nintendo wanted to shake things up a bit with Pikmin 4. Not only did the studio introduce the game's first customizable character and added the brand-new Ice Pikmin mix, but it also threw in an adorable new creature known as Oatchi. This dog-like creature changes the core gameplay loop drastically, and Pikmin 4 players may not know what to do without it.
