White Pearl Subterra Dual Hydranoid 540G in original B1 size. Special Attack series with heavy metal band.

Gently played with condition, but the the left mini head is stuck closed. When the figure pops open on a metal card, the left mini head does not fully pop up on its own. You need to manually raise it up, but the lower jaw is stuck closed.…..see the 2nd photo to see what it looks like after it pops open on a card. Sometimes it will open from a roll, and sometimes you need to drop it on a card. Closes properly.
