Ninja Sixth Grader's Diary. Pirate Invasion

My name is Chase Cooper, I am still 11 years old, and yes, I am still a ninja. This is my second diary. Only a month has passed since my transfer to Buchanan School, but in a crazy school like mine, a month is an eternity. We recently had a day when everyone spoke like pirates, but it didn't stop the next day either... As the week went on, things only got worse, and soon rumors of a mass pirate invasion began to circulate. I ignored the warnings, thinking it was a joke. It turns out... I was wrong. Now my whole school is in danger, and I am the only one who can save it
