Nintendo Land - Solo Attraction - Takamaru's Ninja Castle - Unstoppable Stamp Run

This is another one of those stamps that are the most difficult to get in Nintendo Land. Unstoppable is what I think the second most difficult stamp to get in the game. Same as the Racing Perfection stamp, you must have a flawless run the entire game. The extra levels make it harder because you need to think fast before it's too late, and if you let one go, then you have to start over. It's a mix of quick reaction, but also have a good memory of where each ninja will be. Here is the hardest stamp achieved in Takamaru's Ninja Castle. To get this, you have to clear all of the Main and Extra levels with a 100% Takedown Rate. In other words, do not spare a single ninja, all must be defeated. Taking damage is allowed unless it's your last heart. Wii Remote Assist must not be used to get this stamp. With Wii Remote Assist, multiple Wii Remote helpers can stop any ninja's movements, except for the black ninja. By pointing the Wii Remote at any ninja, you can stop the ninja until the GamePad player defeats it, or if the Wii Remote helper lets go. The Wii Remote Assist method can be considered too easy since you can hold a ninja for 30 seconds, defeat it, and it goes to the next part of the level. That makes this strategy clear the game with the fewest of ninjas as possible. If a Wii Remote cursor is on screen, then you cannot get this stamp.
