Sand Shark
•They don't wander to much near the surface, so it will not follow you if you swim too high. It'll try to follow you from the seafloor and if it cannot, it will wait until you come back.
•They adore being scratched under the chin and will purr when you do it.
•If you sat on the sand, it will sometime come and sat its head on your lap.
•They like to tackle you
•They love to chew, yes it does include your arm or leg. No worry, it's only playful and harmless nibbles.
•You can try to ride on their back, but they don't like that very much. If you do, they will trash around like a rodeo horse. And if you are still holding on despite that, it'll bury itself under the sand.
•If you upset it, it will bury itself under the sand and sulk there.
