This set was one of the ones I remember having the most fun with as a kid. It includes a cheap way (back in 2011 at least) to get Garmadon, who is the most desirable Minifigure in the line. In terms of play functions, it has spring suspension and little cages to capture the ninja in, as well as a skull mouth that closes up and down. My only two complaints would be that it looks a bit too chunky and it should’ve probably retailed for 50 bucks, not 60. Don’t pay more than $75 for it on eBay secondhand.
