I was reinforcing my MP Megatrons feet tonight with clear nail polish and I snapped out his feet. Then I noticed that the actual hole in the foot is very very tight and it looks to be almost impossible to pop the joint back in. I took a look at the underside and took out the 5 screws. I was able to get a xacto knife between the 2 pieces but it wasn't coming apart. Does anyone have any idea how to get the foot pieces apart so I can get them back on MP Megatron?
