When making the change to 3D graphics in Mushroom Kingdom Adventure, (known as "Birdo RPG: Adventure 64!" or "Super Kyasarin" back when this picture was made and released) Birdo's model from Mario Party 9 was animated to walk and breath and then pre-rendered into two-dimensional image animation frames. The above image being frame 8 from the front facing walking animation was released on Luamiana Vinfreild's personal Facebook page, and the old Vinfreild Website Blog.
