Rain Storm

There could be many reasons why the thunder storm has come on Club Penguin, here are a couple:

1. There could be water ninjas coming to Club Penguin.
2. It could be a replacement for the Festival of Flight.
3. It could just pass and nothing will happen except a few puddles. But that's just boring so we won't think that, will we?

I think it will be number one because of a log in screen which says that ninjas should expect a new challenge.
