Tired of your dragon always catching stuff on fire not any more because i know how
to get a purple dragon witch they wont set any thing on fire this is how:
first you buy a dragon nest.
then you rotate-cradle-rotate-cradle untile you cant tell your sim any thing else to do.
repeat that 3 times then you play music and then after about 10 minutes on sims not in real life
take them of.
repeat what you just did until it hatches.
Note:It worked for me 4 times so if it doesnt work for you im sorry! Happy playing enjoy!
