"RAT is the most powerful military in all of ROBLOX. With over 200,000 members, show that you are a part of an unstoppable military with this flag."


The Frostarian Flag is a Common-tier decoration item. It is exclusive for players that are at least rank one or higher in the group RAT (Roblox Assault Team) unless it's won in a box.

It can be won in boxes without the player being in Roblox Assault Team via Mystery Boxes or the Daily Gift, which also occurs with the Frostarium Mine.


  • The Ultimate Update GUI covers up the purchase screens of both Frostarian Flag and Frostarium Mine with a lock screen; however, the buttons are still accessible.
