Why Do Sharks
Riddle: Why do two sharks sometimes eat each other?
Answer: When a shark eats someone it makes a ghost inside the shark that can drive the shark around the sea just like if the shark is a van (a haunted van). If you are a ghost that got eaten by a shark then you (probably) do not like sharks anymore. So when you see another shark you must drive your shark into the other shark to eat the other shark. So if both sharks have ghosts in them then they will both try to eat each other.
