Help me fix it! Bandai Creation Destroyah

[Grunkle Sans]

So pretty much I received a Bandai Creation Destroyah today. I'm not sure if this is common, but his right leg refuses to stay in! It will only pop in half way, either in the top half of the socket or the bottom half, but once I attempt to rotate the joint, the leg just falls back off. I'll try my best to update this post w/ pictures in a few minutes. Thanks for any help!

Try heating it under hot water or with a blow dryer.

I'll try it, but from what it looks like, the circle peg thingy on the leg can't fit into the hole because of the thigh sculpt.

Hairdryer nuff said. Let it get nice and squishy, insert leg and dip in cold water.
