Yamamura

Yamamura is a rock dove with Mario's emblem on the breast who appears in Super Mario Maker. Yamamura 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. Yamamura's way of communication is simple coos, but with words in parentheses translating them. 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.

He is named after veteran Nintendo level designer Yasuhisa Yamamura. Yamamura is not to be confused with the Parakeet, a budgerigar that records the player's sounds in the game.
