MG Acguy’s Eye

For those who have the MG Acguy, are you able to slide its eye inside its head (is it supposed to be able to do that)? I wasn’t able to as the eye piece is pressed against the clear dome and when I tried to force it, it actually made a small crack on it (you can see it in the picture) o_o.  I’m also having trouble getting the inner leg extension (from the pelvis) out as it is too locked up inside. Though I’m having a hard time coming up with any “serious” poses for this thing, I’m having quite a lot of fun messing around with it ^^;.
