Raising a Big Bad Dragon is a huge responsibility. You need to keep an eye on them 24/7 or they'll wreak havoc on your Island. They'll use their huge gusts of breath to blow your habitats over or lie in wait in your Caretaker Cabin, waiting to give you a scare.
Don't leave any clothes out to dry on a clothesline on your Island. Big Bad Dragons - the clever scoundrels that they are - will sometimes wriggle into your unattended garments and slip out of sight. The next time you see your dragon, you may mistake it for a very hairy new caretaker.
Big Bad Dragons love to play games with humans, but rarely are they games humans enjoy playing. For example, one mischievous child terrorized his mother by crying "Dragon!" on their Dragon Isle (the family, being caretakers, were not scared by this as they lived on an island full of dragons). After three times, a Big Bad Dragon took the child in its claws and flew around the island with it. Once safely back on ground, the child learned its lesson about being a pest.
Nothing can shield you from the full force of an Epic Big Bad Dragon. Straw caretaker huts? Don't make me laugh. They can blow those over without getting winded. Building your hut with wooden sticks works just as well. Even bricks are helpless against an Epic Big Bad Dragon. The best advice to stay safe with an Epic Big Bad Dragon is to avoid angering it in the first place.
