this picture shows laser attached to megatron. i don't know how i'm missing it, but i don't see how it works. i do have the united version of megatron but as far as i know it's physically the same as the generations one. can anyone explain it to me or show me a better pic of how this works?

See the red tab on the arm in the upper right pic...looks like the heel of Laser should have a groove that fits over that tab. All it really looks to do is help keep him in place a little better than if you just balanced him on his arm.

I can figure it out soon enough-my Laser/Buzzer set just processed at BBTS and I hit ship.
