Ok, David, here it is. So I transformed one and this is the one that has no problem with the ankle joints. I tried to squeeze them in but after awhile, the legs still pops off from the peg on the backpack. I aligned everything and I thought at first maybe I didn't plug in properly the peg in the shoulder from the legs. Now, even though everything is aligned, the right leg keeps on popping off from the backpack peg slot. It's not a biggie to me, it's just that I'm not so sure why it does that.
