First, you need a mini-screwdriver that is the same caliber as the offending pin. Most $1 mini screwdriver sets have one you can use.2nd, boil your Bakugan in water, do NOT let it touch the bottom. This softens the plastic and makes the rod easier to move.Last, use the screwdriver to jam out the pin, using something solid like a table to press against. If you're having trouble, it's probably the rough end. All pins have a rough end to hold it in place, so make sure that is the end that comes out first.
