do you remember the video that was posted here? to take the leg off that guy put it into hot water.Oh, I considered actually trying to make the other leg ''shorter'' instead of making the short leg longer - to reflect the fact that Mikey actually should be shorter than the other Turtles. However I wasn't able to get that other leg off - even using the hairdryer. I felt like I would have snapped the joint.
p.s. excellent to know it's not a leg length issue.
p.p.s. if you didn't watch that video, find it and watch for sure. it gives a lot of info of turtles inner structure, at least about the legs.
