In the Space Frontier booth, you will come to the Planetary Slash n’ Defense mini game.
This mini games has a small similarity to Fruit Ninja (which I hope everyone is familiar with). The bombs you will want to avoid are the ones with Zergs "Z" emblems. You do not have to move you or slash and of the asteroids to make this count. You can stay idle from begging to end. This will guarantee you never to hit any bombs.
