For a $10 Set, you get pretty good value for what you pay for. You get a hero and villain Minifigure as well as a half-decent build that includes some jungle pieces that could be used for a MOC if desired. The play function is cool but simple, so overall it’s pretty much a must by for the kiddies, because it’s cheap, action packed, and valuable. However, I wouldn’t pay more than $15 for this secondhand on EBay or whatever.

Ninja Ambush is a neat set. You get a fun little play feature, a ninja and skeleton, and two weapons for a small price of $6.99.

Hats off to the person at LEGO who did the minifigures! The fire ninja, known as Kai, has the ninja mold returning after a long time, as well as a katana, but also has a brand new torso and face. The torso features the Ninja clothing with a fire badge on the shirt. No back printing, however. The face is pretty sweet as well- a gruff and serious look with a scar across the eye. That's some cool LEGO right there. The skeleton known as Bonezai features an axe, brand new feet, and a new body mold. That's pretty sweet.

The build is simple and fast. Firstly, you build the shrine containing the Scythe of Quakes. It's a simple build, but it works. The Scythe is a three piece build and it stays together quite firmly. After the shrine, you build the bamboo launcher. The bamboo is represented using brown cylinders and grass pieces, but it gets the job done better than anyway I could've thought of. It's a simple build, but you start to see it come to life as it is created.

There's only one play feature besides having the ninja and skeleton duke it out, but it works fantastically. Set the minifigure in the launcher, then slam your finger onto the trigger and watch him fly. When Kai hits Bonezai, it is among the most satisfying moments in plastic history.

At $7, this is a great set to pick up. It's fun to play with, and you get some great figures. Pick it up if you see it.

Ok I am going to tell you that this is a very good set it comes with the golden weapon with two minifigures and a catapult- like with  a bamboo tree. In my couuntry it cost me 12 bucks that why I put only two blocks on Value for money,the set is prety good and has a good playability but a very fast Building experience it is very small but is good ,but well my calification is 8.0.

i love ninjs, i love skeletons, and i love lego! this set was amazing i especially like the play feature

Pros

• tree actually launches far
• only 7.99
• comes with gold weapon

Cons

• wrong gold weapon for kai
• don't like bonezi's head

this is a very good set for building, playing, and for the money

Ninja Ambush is my favorite "little" set.

Pros

• A very fun, if quick, build. Putting the little bamboo grove together was particularly satisfying because I could really see the bamboo shoots coming together as I built. I may look for more of the pieces used and build some bamboo groves of my own.
  
• Launching the ninja Minifig at the skeleton Minifig never fails to make me smile, particularly when the ninja knocks the skeleton over. If that's not playability I don't know what is.
• With two Minifigs and the super cool camouflaged ninja launcher, the $7 price point is awesome.

Cons

• I don't really care for the feet on the Ninjago skeletons. I haven't picked up any sets with the little spinner bases, but it looks like the feet are probably necessary for the spinners to hold onto the skeletons, but I think they just look silly. That, of course, isn't really a problem with this set so much as it's a problem across the theme.
• I would have preferred if the piece that sticks out in front of the bamboo grove weren't bright red. Brown or even black would have looked much better and been less disruptive to the illusion that the skeleton is walking past an ordinary bamboo grove and has no reason to believe that a ninja is about to come flying at him.
  

Pick this set up and fling a ninja!
