BIONICLEsector01
“The Kurahk set was released in summer 2003 as one of the six Rahkshi sets. By combining pieces from Kurahk with 8589 Lerahk and 8592 Turahk, one can build the Rahkshi Kaita Za. Instructions for another model that combined pieces from Kurahk and 8589 Lerahk were included in a... More Kabaya-associated bundle.”

“Lerahk is one of the six original Rahkshi types released. In the BIONICLE universe, they have power over poison, and their staffs had to touch its target in order for it to have an effect, unlike most Rahkshi's staffs. Besides a Lerahk itself, the set comes with the Staff of... More Poison and a green Kraata. If the set was bought at Wal Mart during a limited time offer, instead of coming with its usual green Kraata, it came with a Shadow Kraata instead. They are not the smartest of the Rahkshi, but they are still strong, fast and cunning and their power is enough to destroy things with ease.”
