Martian Series (HGD)/Rocky Road 1/Grey Mask Twister

About
This enemy constantly fires freezing snowflake mines in random directions even when not attacking a character. This means that even if a Grey Mask Twister is close to a character, the latter will not always be hit by the projectiles. This enemy is more of a nuisance than a threat, as the active mines stay on the screen for a few seconds before disappearing, potentially leading to many snowflakes being left on the screen.
