Backstory: On the toa Inika’s journey across Voya Nui, the mask of life gave sentience to a random rock just for fun. He was so happy to be alive and he wanted to name himself something awesome. He comes up with the name, “The Mountain”, but that name was taken by a GOT character so he couldn’t use it. So he downgraded a bit and went with the name, “The Boulder”, but he couldn’t go with that because it was the name of a ATLA character. So then he finally goes with, “The Rock”, but even that name was taken by a famous actor. So the creature finally goes with, “The Pebble”, at least until he finds out that name’s taken.
