The BIO Code Red Mask Sticker is a BIONICLE themed Sticker. It appears to be Malum's mask. It can be obtained from Raanu by entering Malum's BIO code here. Gresh's canister has the same BIO code printed on it, and thus entering it will yield the same reward. Gresh was later released with a different BIO code, which players can use to get the BIO Code Sand Flag Sticker.
