The Three Little Pigs... Remixed!

The three little pigs were visiting their beloved Momma Pig. After building a snow-woman to honor her, they came back inside and started to drink a cup of hot chocolate.

Only a few minutes later, the Tiny, Dire Rat came along and started to squeak, "Big piggy, big piggy, break down your wall, or I'll chew and I'll spit and I'll eat your house down like a termite!"

However, the pigs didn't want to give their house up so they said... "NO!!!"

When the rat started to eat the wood of Momma Pig's house, Danny Dog was walking by. He saw this and he did not like it! So, he quickly went back to his house and got his machine gun.

Then, he went up to the Tiny, Dire Rat and barked to him, "Who do you think you are eating up Momma Pig's house!" However, right after that, he saw a cat. A big, plump cat just lying around. Obviously, Danny Dog got sidetracked.

When Danny started to chase the cat, he found out that even though it was fat, it was pretty fast. All this time, the Tiny, Dire Rat was eating up Momma Pig's House!

Well, in the end, the pigs became homeless and died of hunger, and the Tiny, Dire Rat became so tired of chewing and spitting that he fell and never got up again. After chasing the cat for an hour, Danny shot it with his machine gun, but, right after that, he was so tired that he fell down and didn't get up either.

Moral: Get a mousetrap!!!
