Yoshi'd make a better Rudolph if he just painted his already huge and round nose red. Then he'd be like one of those vehicles from the Yoshi's Island games.
....hell can Yoshis turn into VEHICLES, anyway? It's not like Baby Mario RIDES them at that point, it's the one time he DOESN'T.
(Somewhat) Interesting thing I've noticed about this image, it's a pre-release image from 2010 Wii but the icon used for Peach on the top left appears to be from 2008 Wii, as she's wearing her vest top from the summer Olympics- her arms are obviously bare rather than the magenta for her winter top.
