Huh! I always assumed Goombas bumped Mario to death, but now we know better. Thanks for clarifying, Miyamoto-san, and for passing on the information, Sato-san.
I heard that someone once asked Miyamoto-san why Mario takes damage when he bumps into a Goomba from the side in the original Super Mario Bros. game. Apparently, he answered, "It's because the Goombas bite him." … Yes, and when they bite you, they'll do it with a smile on their face! (Laughs)
