How to Play
From Bunni Wiki
Use your mouse to control your Bunni avatar (the Bunni with a crown). Just click and drag! There are various quests available in the World of Bunni and the main objective is to marry the Bunni girl and fill the island with hearts. To be able to advance, you will need resources that you can gather by ordering other animals under your control to work. These animals also need food, so you should make sure there are fruit trees or flower gardens nearby. Take care of your ecosystem and you won't have to keep things up yourself. If you balance the number of workers with the amount of trees/rocks and food, then you can go off and do quests and such while earning wood and rocks. :)
