For those not familiar with ArtifexCreation, it is a YouTube channel that does stop motion build reviews. It is basically a sped-up cleaner version of Eljay's Build Up, but it shows off minifigs and functions. They often review Ninjago sets early, and I have found three 2015 summer wave reviews here. You can see the minifigs, build and functions. Interestingly, the ghost things in the sets appear to be able to attach to the Ninja's heads. So check it out and discuss here!
