Look Out for the Ninja
Ninja warriors are known for being sneaky and elusive as well as deadly. As soon as you spot one, that usually means your time’s up because no way could you outrun one of these guys. It’s probably best not to be seen reading this poster either, just in case that’s how ninjas are finding people! So move on, don’t think of ninjas and don’t talk about them either.
Even whoever created this poster seems to have vanished. Scary!
