Just in case of emergency, kids should be carrying their own rifles. You never know when a gorilla is going to escape and you are going to have to save the day!
I know it is just an air rifle, but you have to strain to see that. Plus, the cartoon really makes you think it is real--the gorilla did! Note the girl carrying a bow and arrow. Note also that the two kids simply carried these into the zoo!
Also, I find it fascinating that the zookeepers don't have anything--or are they hiding rifles? Is that why the gorilla knew what a rifle looked like?? Animal Cruelty?
