To get to the next island, explore the current island thoroughly and save everyone. Save berries by clearing the minimum amount of trees, ice and rock. You can return later when you need more shells or other items.

Small mountain landmarks that have an item icon above them will appear on islands. When you tapped, you will get a random prize from a roulette wheel. Sometimes baby animals will be trapped in them. After collecting your reward, the resource node will start a cooldown timer.

When on the map screen, there will be two icons next to the selectable islands (a paw and a torch). The paw displays how many animals still are remaining on the island. The torch shows you what important items are present. Collect all of the animals and items before moving onto the next island. If the final item or animal is locked in a slot machine mini-game, be patient until it appears.

Your progressed is saved on the last two islands that were visited. When you find an island that has several slot machine mini-games you can return there and play them again as many times as desired as long as you have not traveled more than one island away.
