Justin, those two pegs are the hole for the screws that hold him together. They can be sanded down with sand paper, but I'm not sure if you'd be able to put it back together.
The metal pegs?
Metal pegs? My Neon Ventus one doesn't have any. Also, I spin-rolled it onto a gate card without the screws, and here are my results:1/3 of the time, it rolls normally, opens normally.1/3 of the time, the top half pops off when it rolls onto a card.1/3 of the time, the top half spins like a normal spin Bakugan.However, there is a set amount of power you should spin it with, so practice and skill can help you control the outcome better.
