The house was made of

Blue berry muffins.  These were no ordinary muffins though, they were as hard as cement, and the blue berries were actually missiles, diligently protecting in inhabitants.  Just then a wobbly old wagon rolled up to the front door. The blue berry missiles silently locked into the foreign object, waiting for a threat to appear.  An old man stepped out of the wagon, his beard fire red and falling all the way down the dust on his shoes.  He squinted looking around the house, checking for any spy's trying to learn how to get in.  A voice code lock appeared from behind the muffins.  He whispered the secret password into the machine, uttering the word so quietly the machine barely picked it up "Gabby".    The door immediate swung open and the man hopped inside and slammed the door shut again.  With a smile on his face and a twinkle in his eye, he knew he was safe and sound in his house.
