I'm A Little Crabby.

I’m A Little Crabby is a game of secret hand signals, suspicious friends, and hidden identities. Pick a partner and establish a secret signal, then collect a set of four matching cards. Once you get a matching set, try to tell your partner by using your secret signal. Be careful - if your opponents intercept your signal first, you lose a point.
