|Greenswe is indecisive, but stylish.|
The Green Dragon Mask is a clothing item exclusive to former game moderator @Greenswe, awarded on October 14, 2013. It is unavailable to any other players who try to obtain it.
When worn, it spawns a green dragon which follows Greenswe around, the Dragon breathes green fire in the place of using the Fist. The item had the same benefits as the Dragon Hand and its variants: pushing other players farther and doing more damage to blocks. However, when worn together the effects would be applied twice, making it too strong, and hence those effects got removed.
The In-Game Information of the mask hints that Greenswe took a long time to decide his Moderator Item.
