Realistic Fictions Story

In language class, we are making a realistic fiction story.  My story is about a kid named Joe who goes to school like every other day, but when it is lunchtime, everyone is so hungry that they turn into cannibals and start chasing him.  Everyone was a cannibal that is, except Joe because his mom made his lunch so he is full.  So everyone is chasing him, even the principle, and he finally has the idea to go back to the lunch room and make walls out of lunch tables around him.  Then he calls 911 and Pizza Hut.  He calls Pizza Hut because they can bring pizzas to save everyone from starving to death... while the police handcuff everybody.  There is only one person among the dead, his language teacher who got eaten by his friend.  I think it will be good!  :)
