LEGO ^® SHOP at HOME has placed the BOHROK-KAL descriptions online. Use “Item Number Search” for Item numbers 8573 through 8578; e.g. Here is NUHVOK-KAL . They don’t show up under the “BIONICLE™” link in “Shop Favorites” yet.

The surprising part of the descriptions is this:

Look for 72 Limited Edition genuine Sterling Silver Krana-Kal and 5,000 Limited Edition silver-colored metal versions in Bohrok-Kal packages. They’re randomly packed so you never know where the power of Silver might be found!

I find this absolutely shocking, given that the BOHROK-KAL are packaged in clear, transparent pods.
