This time April buys some ancient Japanese antique which turns out to be a time septer and she switches places with a Japanese king's son.So the turtles have to go and get her and return within'a 48 hour period.Not all that interesting,event tamer than part 2.The best thing about this is Casey Jones,and the 4 Japanese guys, who switch places with the turtles,watching hockey and playing video games at the bar.
