Spore: An Arm and a Leg

The Creepy & Cute expansion for Spore was a very poor bargain for its price and what was included.  However, it led to Maxis and EA wondering just how bad a deal they could get away with.  Thus was born Spore: An Arm and a Leg, an expansion which includes one arm (Suckerpuncher) and one leg (Yankleg) for use in creatures.
