#shell creeper bite

A detail people have noticed is in Super Mario Bros. Wonder when you are hit by Koopas they bite. Here's the thing, this is not the first time Koopas have used bites as a form of attack.

If I am correct in Super Mario Galaxy if you run into a Koopa at the front it will bite you. But what's more notable is in Mario Bros. Arcade the Koopas aka Shell Creepers bite you if you get too close, with sprites depicting this.
