I decided to splurge today since it's my birthday, and I made my biggest TF purchase yet, MP Grimlock. I opened him up when I got home and I got an unwelcome surprise once I transformed him...his waist just flops around. Is this how his waist is supposed to be? Or is my Grimlock a victim of bad QC? Me Grimlock no like floppy waist and spring action dino head!
