Bribe the war hippo

"Listen buddy," you say to the war hippo, "You like fish, right?"

  The war hippo tells the other five guards to get back to their posts.  After they comply, the turns to face you and says, "What does that have to do with anything?"

  "But you do like fish," you persist, "I mean, all hippos like fish, right?"

  "Of course I like fish!  I’m a hippo!  Hippos like fish!"

  "That’s quite the coincidence, because I happen to have a lot of yummy fish on hand, if you get my drift"

  The war hippo catches on.  "Like how many fish?"

  You perform the necessary arm waving to cast oFish causing a torrent of yummy fish pour in from all angles, burying most of the other guards alive.  Turning to the hippo you say "Will that be enough?"

  You receive no response from the war hippo, mainly because he’s busy stuffing his giant mouth full of yummy fish.  You take advantage of the situation, and sneak into the top secret military base.

  Inside you find huge room containing a maze of cubicles.  Each cubicle contains exactly one top secret military pencil pusher.  Fascinating sure, but what really catches your attention is a single door on the eastern wall of the huge room, marked by a sign that says, "Keep Out."  Cool.
