I put together all of my Series 4 Mixels, so I figured I would share some better pics.
Orbitrons - Rokit, Niksput, Nurp-Naut
My favorite out of the bunch is easily Niksput. He's got five ball joints on him (arms, legs, and upper jaw), giving him tons of poseability and personality. Second favorite is probably Boogly. I'm a bit disappointed with Meltus--I love his baby T-rex form and his eyebrows are fantastic, but the lack of an opening mouth definitely hinders him a bit. His neck can move up and down, but...ehh.
Oh, did I mention that you can also transform Niksput into a simple Minifigure flying platform? Because you totally can.
I really,
really like Mixels.
