Oh, you're trying to get the Demon Dragon, huh? 85 gems in 4-5 is not possible unless you're buying them, earned them, or someone gives them to you.

How about offering your mum what she wants in exchange for what you want (gems)? You need US$10 worth of gems. I'm sure you and your mum can work something out.

I'm buying gems for my son, in exchange for doing stuff that keeps his mother happy. :) Like doing his homework every day (he never used to), being extra nice and polite to everyone, doing chores, doing well in his studies, etc. Go think about it, and maybe talk with your mum. :) Good luck!
