Yamamura

Yamamura, not to be confused with the Parakeet, a budgerigar that records the player's sounds in the game, is a rock dove with Mario's emblem on the breast who appears in Super Mario Maker. He is named after veteran Nintendo level designer Yasuhisa Yamamura. He is a companion of Mary O and Undo Dog, frequently appearing alongside them. According to Mary O, Yamamura is a skilled level creator, and Yamamura has a section that includes ten design tips for making better levels. His way of communication is simple coos, but with words in parentheses translating them. According to official bios, Yamamura likes eating edamame, soybeans in the pod, and taking long walks in the park. Yamamura has also created levels that are part of an officially released set of levels, the first of which was Coo! ("My First Task" Edited), an edited version of one of Mary O.'s courses.

On January 12, 2016, Yamamura was released as a Mystery Mushroom costume, which can be unlocked by clearing the Cooooo! (Feat. Yamamura) Event Course.

Super Mario Maker bio

 * "He's a pigeon. That much is clear. For reasons beyond our understanding, he's also a master of Mario course creation. He loves edamame and long walks in the park."

 * Mary O.: "Wow! Everyone's having so much fun uploading the Super Mario Maker courses they've created!"
 * Yamamura: "Coo." "(Your words ring true. Over two million courses have been uploaded to date.)"
 * Mary O.: "Make that over two million AND ONE. I made one too! Can you try it out for me, Yamamura?"
 * Yamamura: "Coo..." "(As you wish, my apprentice. Here goes nothing...)"
 * Yamamura: "..."
 * Yamamura: "COO?!" "(What is this monstrosity?!)"
 * Mary O.: "OH DEAR!! Is it really that bad?!"
 * Yamamura: "Coo." "(Yes. It really is. I'd rather bunk with a Bob-omb than ever look at that disgrace again. Now I'm filled with a burning need to show you the error of your ways.)"
 * Mary O.: "You're quite...honest, aren't you? OK, so what didn't you like about it?"
 * Yamamura: "Coo." "(To start, everything. It's full of awful ambushes. Thwomps placed above the screen where the player can't see them. Lava Bubbles leaping out of nowhere. That's not coo.)"
 * Mary O.: "What do you mean? Surprises are fun!"
 * Yamamura: "Coo." "(Fun for who? For players, the fun comes when they notice an ambush in the nick of time and evade it. If there's no warning whatsoever, that's no fun at all.)"
 * Mary O.: "Oh, I hadn't thought of it like that..."
 * Yamamura: "Coo." "(Clearly. You also used too many enemies. With so many foes attacking from all sides, the player is in a constant state of tension and confusion. Courses are more enjoyable when there's a balance of calm and chaos.)"
 * Mary O.: "Hmm, that makes sense! I'd really like to get better at making courses... Do you have any tips?"
 * Yamamura: "Coo. Coo!" "(Only if you buy me some edamame. My massive pigeon brain needs fuel! Now then, let's start by making a course with the player in mind. In fact, that's your homework for this lesson. Make me proud!)"
 * Mary O.: "I'm on it! I CAN DO THIS!!"
