I came across this tree in Gimme Gacha Central..and what a good idea it is ...so if you need to clear your inventory of a few extra unused gachas? Please consider donating to The Giving Tree! Your generous donations will be used to for special free community events, parties and giveaways! Gimme Gacha gives away OVER 25,000 gachas to the Community each year so every donation helps!
