Chrome and scorch I got it on my first try
OK the best chance for a rainbow dragon is below
Blue fire (first) + Crystal dragon (second) Please Note: you will have a higher chance if you have an extra Rainbow habitat and if Both dragons are level 10 or higher. the incubation time will 48 hours if it is a rainbow dragon, sun dragon, or moon dragon
*****READ*****
The combination of Blue fire dragon (first) and Crystal dragon (second) can also be used to get the Sun dragon and also the Moon dragon
*****DISCLAIMER*****
You are not guaranteed to get the rainbow dragon, the sun dragon, or the moon dragon this is just the fastest way.
Hope you enjoy :)
The anwser is simple, you just have to combine any dragons that has a earth and water type yet you should remeber that this is a trial and error thing you may for another drugon such as Mud but keep on breeding you could still sell the dragons that you don't need.
well first you have to find a unicorn and a dragon then get both of them together but make sure the dragons mouth is shut or he mite try to eat the unicorn aslo the dragon has to be a male and the unicorn a female or other wise they will not mate but they will not mate in the first place unless you get both of them drunk as hell and that is how you can have a unicorn dragon.
