A tsunami breaks your bones, not from hitting you, but from making the ground slippery. The water from the tsunami made all the sidewalks and stairs too slippery to walk on, but you tried anyway, slipped, and broke a couple bones.
As you struggle on the slippery ground you hear a loud yowling sound. You turn and see a bunch of stray cats (かつ) slipping and sliding too. They're coming right for you, uh oh!
