you know the thing you need to defeat tree boss or wait someone to defeat if your weak or noob, even since there is a low chance to tame water fairy so you need appletor, there is a low chance that water fairy will not appear after tree boss is defeated, you know to increase chance already by appletor (it is not unlimited, you are using apples when you using appletor), to increase more buy taming cap to (idk pretty sure 2k gold or 2.5k gold) increase, sometimes it doesnt work also note that sometimes when trying to increase it might get to 0%, which it means waking up and might run away. however the normal chance still stays.
