After a fun day of building snow forts and snowball fights, Sam didn't want the fun to end. So we invented "Fun Ball." The name was taken from an episode of Caillou that Sam remembered where the characters on the show were so bored they ended up making their own game called "Fun Ball."
So on this snowy evening, we made up a game that continued his fun of throwing snowballs. We rolled up chunks of play dough to use as ammo in our war.
