Pudus, like all of us, sometimes trot ahead at full speed without noticing where they’re going.  And sometimes they run their teeny faces directly into a small little hill.

Pudus usually say, "urmphf."  And then they keep going.  Just like we do.

(Actually, yes, this picture is really just the camera turned a little slanty.  Sometimes pudus see old episodes of Batman and think the wall-climbing bit was funny.  Pudus laugh and laugh.  Then they go out and pose, hoping someone with a camera will come along.  In this case, someone did — Wilfried Berns, and the photo is available under a Creative Commons ShareAlike license.  This made the pudu very happy.)
