Oceanic winds can often wash the blue dragons up onto the shore, and people may come across them on beaches. It’s important to know, though, that they are still able to deliver their sting, even after they die. So the best choice is to just let them be, and admire this real life Pokémon from afar.
Some people may even consider adding this species to their aquarium, even though they don’t make really good pets. First of all, it’s impossible to stack up that many Man o’ War for their dietary needs, so unfortunately, the dragons that are kept as pets often starve to death. Also, you’d be risking a painful sting from both the dragons and the Man o’ War.
