Write a fable (short story conveying a moral) for your Clan.

For example, several StarClan cats get into an argument into whether an animal can change its nature. They change a mouse into a cat. But in battle when confronted with an opponent, the cat flees, showing that despite being in a different form, true nature is always revealed. (This is adapted from The Cat-Maiden)

Or, a ThunderClan cat witnesses a RiverClan warrior catch a fish with ease. The ThunderClan cat, wanting to impress their Clanmates, attempts to copy the RiverClan warrior and is washed downstream. This shows that "thoughtless imitation will end in danger" (adapted from The Eagle and the Crow)
