Once upon a time, there were three penguins. The mother penguin was very poor. She did not have enough money. So she always made her own food.

So when the three penguins named Ivy, Chase, and Ralphie were all grown up, they waved farewell to their mother.

Ralphie, the first little penguin, built his house out of cheese.

Chase, the second little penguin, built his house out of pretzels.

Then Ivy, the third little penguin, built her house out of nice and inedible bricks.

"Open the door and let me in." said the big bad polar bear. "Not by the feathers on my chinny chin chin." said Ralphie. "Then I'll scrunch and I'll crunch and I'll munch your house in." Threatened the big bad polar bear.

So he did. The big bad polar bear ate Ralphie's cheese house in one big gulp.

Ralphie was in panic and despair. He ran to his brother's house.

"Open the door and let me in." wailed the big bad polar bear. "Not by the feathers on our chinny chin chins." said Ralphie and Chase. "Then I'll scrunch and I'll crunch and I'll munch your house in." Threatened the big bad polar bear.

So he did. The big bad polar bear ate Chase's pretzel house in one big gulp.
