One day there was a boy named achilles and his mother who wanted to make him safe forever.  There was a river called Styx that people said would make you immortal so Achilles' mother took him there when he was a baby and held him by the ankle, dipping his whole body in the river. 

.

From that day on Achilles lived his life worry free! his whole body that touched the River Styx was then immortal. But Achilles and his mother did not realize that because she was holding his heel, that part of him was not free from harm. 

One snowy winter day, Achilles and his friend Paris go outside to play and decide to have a snowball fight! 

They were both having a lot of fun throwing the snowballs back an forth at each other and it was all going great!

OUCH!

Until one of the snowballs accidentally got a rock in it and it hit Achilles heel!
