HELP- I can't take off this minimates helmet

Posted in Off Topic

I just got their Heralds of Galactus set & I can't get Galactus helmet off...his head just pops off. I'm new to minimates & don't know what to do. It's on totally crooked & looks awful. This is a gift & I can't give it looking this stupid. How can I get the helmet off???

What I've tried so far is insert m finger nail and run it all around the base of the helmet in hopes of loosening it. And I put paper over the ball joint to make the head fit on tighter & attempted to get a wiggle goin, but it's nothin doin. If I could just rotate it so his face is centered int he helmet frame I'd be happy.

{edit for typos & to update with what I've tried in order to remove it}
