they're the easiest to get because they're the only dragons with those elements that can be bred

Neon is the only dark+electric type to be bred

Penguin is the only dark+ice type to be bred

Zombie is the only Dark+Metal type to be bred

They may add more dragons obtainable by breeding but until then this info stands true
