*It's a sunny day on the beach and you're taking in the fresh ocean air as you stroll barefooted through the sand.* *Suddenly, there's a sharp pain in your ankle. Looking down, you see a litte red crab pinching at your skin, glaring up at you with his eyes on two stalks.* *He waves his pincers back and forth at you angrily, seemingly taunting you. You must have crossed into his territory, and the brave little crab came to defend it.*
