Toa Canister
From Lego Bionicle
Toa Canisters were transports in the shape of a pod that carried Toa from one island to another across the Great Sea. These canisters were crafted by the Unknown insane Matoran in Karzahni's lair. The makers of the Pods used an odd form of logic in the construction. Namely that they were made in groups of six, because the seventh Toa (Takanuva) would come in the dark times. No seventh Canister, no seventh Toa, no dark times. These pods had beacons that would respond to the the activation of Toa Stones. Toa Canisters could be used by other beings once they were discarded, such as the Piraka.
Most of the canister sets come in some form of Toa canister with a few exceptions.
