Sadly that is NOT fair for either of those! ( sorry for late reply ) A pet dragon or unicorn in my way of thinking things is worth atleast 2 legendary vehicles/riding potions each if they are non rideable but if they ARE RIDEABLE they are worth 3 legendary vehicles/ riding potions! I hope this helps :) ( IT also might take a while to find the right person to trade with since a lot of legendary pet owners are picky )
