How do you get free shiny on backyard monsters?

hardly people know how to get shiny for free but the secret is click on mushrooms then take it some mushroom are with SHINY and i got alot of shiny after all or you can do offers

keep playing hard and producing more winning battles, construction or buy 500 shiny for $5.00 (i would never do it, its a rip off)<<<<<<this is hard

there is a way,do more easy quests,pick mushrooms and if your lucky youll get shiny,upgrade buildings,thats it!3 lazer
