Pufferfish

Pufferfish lives at the bottom of the ocean. He loves spending time there, building sandcastles. The problem is he must be constantly alert because there are many bad fish around. Lucky enough, he knows how to scare them away. Every time he is approached by someone, Pufferfish just puffs up and looks bigger. The fish usually turn tail at this sight – until Pufferfish meets one with the same ability.
