After all this time, I still have fond memories of buying and building BIONICLE sets, both from the G1 and G2 lines. ^^
Even 17 years later, I still remember the day when my aunt took me to a small toy store in a mall and bought me my very first BIONICLE set.
Mine was Toa Onua Mata, and he's still on my shelve, and now wearing a gold Pakari. :3
