The story is about three little flies who build houses out of different materials. The dumbest fly builds his house of grass, which a hungry frog blows down when the fly refuses to let him in. The second fly builds his house of leaves, which the frog also blows down. Both flies then go to their smarter brother's mud house for shelter, with the frog following to huff and puff again.

1. The Three Little Fly’s
By, Andy
Once upon a time there were three little fly’s. One day they all decided to
move out. So the very next day they moved out. The 1st fly was pretty dumb
and he built his house out of grass. The 2nd fly was a little smarter than the
1st fly and he built his house out of leafs. The 3rd fly was the smartest and he
built his house out of mud. One day there was a hungry frog walking by the
house of grass and saw the fly working on his house. The frog started to hop
to the fly but the fly saw the frog coming and ran inside. The frog got to the
house and said “let me in or I’ll huff and puff and blow your house down”.
The fly answered” not on the hairs on my chiny chin chin, so the frog huffed
and puffed and blew the fly’s house down. The fly was standing in the
middle of the pile of grass. Then the fly started to fly away. The fly flew to
his brother’s house; he was also working on his house. The fly saw his
brother coming and asked” why are you fling so fast? The fly answered”
there’s a frog trying to eat me, and he blew my house down. Oh here come
inside. The fly went inside. A couple minutes went by and the frog came.
He saw the house and went up to it. He said let me in. The fly’s said not on
the hairs on my chiny chin chin. Then I’ll huff and puff and blow your
house down. So the frog huffed and puffed and blew the fly’s house down.
The fly’s flew to the 3rd brothers house and the frog fowled
