It's All About Minions ..

 Last Winter, I got hold of the Minions -The Rise Of Gru, set 75551.

I'm a major fan of these characters, so it was great that LEGO featured them in a very cool offering.

The set centers around a pair of brick-built Minion mechs that swing open in the back to reveal highly detailed interiors.  The large knob inside at the top turns a mechanism that spin the Minions' eyes (or eye, as the case may be).

The set allows one to build mechs of Kevin, Stuart, and Bob.  The major downside is that there are only enough parts to build EITHER Stuart or Bob.  It would be nice if all three could be displayed together.  This is a major gripe that I've seen from nearly all online reviews of the set.

Also included are the Minifig versions of the Minions three.

A very cool set.
