Plot hole: When the 3 ninjas' Grandpa is in hospital, he phones them and complains that no-one at the hospital speaks English. Not only is this a strange complaint to make about a hospital in Japan, but later in the film he is seen speaking in Japanese. He should therefore be able to easily communicate with people at the hospital.
