This enemy only appears in Snowfield 7's boss screen, accompanying the White Boss Castle Snake in a huge swarm of 99. It can easily destroy characters that are caught within the mob, especially if all characters were frozen by the boss's attack. Even by themselves, they can swarm over characters easily. The combination of this enemy and the boss makes the boss screen very difficult for an unprepared team. Freezing this enemy with the Magician's Freeze Explosion 6 is a good way to halt their advance on the team, but take care to ensure that the Magician does not get caught in the actual boss's freezing blasts. Fire type weapons are also great against this enemy. It would be wise to bait and distract the boss as well, ensuring that the bait doesn't also attract a large number of these enemies, thus ruining the point and possibly leading to the death of the bait upon a single misstep. If applicable, the Poison Spirit 4 can turn this threatening mob into nothing with little effort.
From Stick Ranger ver12.5 to ver18.6, this enemy was considered a stage boss, as it fit several criteria at the time. However, with the introduction of the Volcano in ver18.6, a redefinition of a boss eventually revoked this enemy's title as "boss".
This is the only non-boss enemy to only appear on a boss screen.
