The sonic boom shot through the nearby cave, becoming amplified by the dense rock walls.  The loud noise came as a surprise to the cavern's lone resident.  Having been in a deep slumber for untold years, the creature woke up certainly groggy.  Uncoilding and stretching its plethora of tentacle appendages, the beast picked itself up from its watery nest and began to move towards the entrance.  Visitor's perhaps, it thought, having been lonely for the many past ages.  Its sluggish, central blob-like body, 10 feet in diameter, slithered against the wet, rocky terrain with the help of its many "arms" pulling and pushing its way along.  Excitement then overtook the creature, changing its usual purple color to a bright red.  Once it reaches the entrance of the cave it pulls itself to the ceiling and begins to release a strong odor.  If the beast is lucky and there are any females around, they might be intrigued by the intoxicating smell and decide to take shelter in "his" cavern from the hot, humid  jungle.  With fiery, anticipation but with perfect stillness the horny beast lies in wait above the cave entrance, semi-camoflauged in the planet's strange flora.
