Rainn Wilson did his own stunts.

In the classroom Patriot tears off one of the girl's ponytail. Later she is digging under the school fence with both pony tails visible.

After the credits, Hitachi makes another appearance.

There is an alternate ending to Cooties (2014) which was the original one, but Lionsgate paid them to re-shoot the ending After killing Patriot, they realize they are out of gas. They venture on foot and eventually find a deserted campsite. They enjoy themselves. Clint throws his novel in the fire and tells Lucy that he is not a writer and says he is actually a teacher, living in Fort. Chicken. Clint has a strong feeling of dread and tells the others to join him. They find the leader's dead body, and the other infected children find them. Then you see infected Boy Scouts, led by Shelly, looking even worse than ever; her eyes are hollow black with more blisters. It's unknown what happened to everyone after the encounter. Carnival music begins playing as three managers from an amusement park, a theater and a family fun center, respectively, get the chicken nugget boxes out of a truck carrying them. Because this ending was never shown, it is possible that the nuggets were also infected with the virus and is responsible for the outbreak.
