forget yeah. After digging in one of the lego bins under my bed, I found a bunch of Bionicle stuff.
Onua's mask (forget yeah,) some weird rubber masks, oddly colored Bionicle heads (red and dark gray,) a second Tahu mask, some of Onua's leg and arm parts, and Gali's head (no mask yet, though.)
Also, while researching those weird rubber masks, Google thought I was searching for:

I was typing in "Bionicle Rubber Kanohi Mask." Speaking of those, does anyone know what they were for/what they came in?
EDIT: Found one of Onua's claws and both feet attachments for Pohatu :D
