Woof Woof!!
Imagine you're a Toad sitting in the woods, minding your own business.  Suddenly you hear something coming your way.  You hear a commotion that turns from a subtle rumble to a forest thrashing thunder.  Then the tree next to you is uprooted and swallowed whole splintering down this wall of teeth.  You jump out of the way and turn around just in time to see a small carrage following after with a Koopa Troopa inside. Congratulations you're alive.  Thought of this at IHOPs and ran with it.
