Canon

This page lists what is actually canon to the Turtle SMP.

According to canon, each character has four lives. If they hit zero, they die, but they can occasionally come back as a ghost (this was voted on by other members) from a ghost town.

Currently, every character has all four lives, except Turtle, who lost a life in Day 1 due to sand falling on top of him. It was decided this would be canon as such a big deal was made out of it in the original video, so the members thought it would be funny to make it a canon life.

In the canon universe, Moon used to be in Memeville, but moved out to her base with Tsurei in order to further research the End (or in Tsurei's case, the Nether).

Currently, every member but Peeky and Boris are participating as characters in the main plot of the Turtle SMP canon (this is excluding inactive members, like Septyl). Some have confirmed they would rather be background characters, but are still technically participating nonetheless. It has also been confirmed that even though they're not really in the mainstream canon, if Peeky and Boris are killed in a major event such as a war, they will still lose a canon life.
