Resources

There are two main resources in Forest Island. The first is **Energy** and the second is **Hearts**. The counters for each of these resources are displayed along the top edge of the screen. The goal of gaining these resources is to restore the land and invite animals to come and live there.

## Energy

Each island, or section of the main Forest Island, passively generates a certain number of energy units per second based on it's level and degree of restoration. You can see the energy gain as a little yellow bar in the air, just above each landmark. Energy output ticks will be shown as a small number once the bar is full. If you open the land upgrade menu, it will also display the energy production as "energy per X number of seconds" in yellow.

As you accumulate energy, these units can be used to level up each island zone you currently have unlocked, Leveling up a landmark increases it's energy output. Once the required level has been reached the game will prompt you to restore the land or access to new areas will become available. Each time you restore the land more things will be added to it. Sometimes its more greenery and trees, other times its additional sections of land like mountains or small islands, etc. This cycle up upgrading and restoring will continue to happen until a given area of land has been 'fully restored' and 'Rest Mode' is achieved. Each island area has different restoration level requirements. For example, the Tree of Rest is fully restored at level 10 where as Bear Den is not fully restored until level 35.

Once a landmark has been fully restored, further upgrades will increase energy output but will not add any additional land features. As you complete restorations, more islands or sections of the map will be unlocked. At the time of writing this page, the main island has 13 sections in total, each with higher and higher energy unit requirements. Thus, the more you progress, the more energy you need to continue to the next area.

### Ways to Collect Energy

1. Passive Land Generation
2. Summoning the Albatross
3. Summoning the Sea Otter
4. Cleansing the Land
5. Printing Photos
6. Energy Tickets
7. Random Energy Bundle from Hatching Eggs
8. Special Animal Summons: Shark (from Seasonal Summer Pass Rewards)

## Hearts

Heart units are passively generated by the animals present on each island section. Similar to energy, hearts can be used to upgrade the various animals you have invited to live on the land, increasing their heart unit output and the number of animals you may invite. The existing animals have to be upgraded a certain number of times before the game will prompt you to invite another of the same type.

> Note that only invited animals are eligible for heart production upgrades, where as special animals from seasonal events or baby animals have static bonus effects. Rare animals, such as the silver fox, can be upgraded via collecting cards from opening chests, which in turn, upgrades their bonus effect. There are also two legendary rare animals that come from cards, these are the flamingo and the monkey (both give a '1000% more Hearts gained' bonus!) (I believe the monkey to be the most difficult rare animal to unlock, with its cards having the lowest drop rate).

Each area of land has a cap on the number of animals you can have active at a given time. This varies from one area to another. You can activate and deactivate animals using the 'Animal Pen' menu (box icon in the drop down menu displayed by clicking the down arrow in the vertical menu along the righthand side of the screen). Some animals are able to inhabit more than one section of the map. For example, you can have pelicans live on the Beach, Seal's Rest, or Racoon Trees. This will be covered in greater depth on the Animals page.

### Ways to Collect Hearts

1. Passive Invited Animal Generation
2. Summoning the Dolphin
3. Summoning the Sea Otter
4. Heart Tickets
5. Random Heart Bundle from Hatching Eggs
6. Special Seasonal Event Actions: Giving Pumpkins to the Cat (Halloween Event), Giving Coconuts to the Shark (Summer Event), etc.

### Cherry Blossom Heart Buff

This charming buff gives increased heart generation for 15 minutes and can be used twice per day. It is activated by opening the Mailbox menu and tapping the reward button in the banner at the top. Once you successfully receive this reward the ambient weather shifts, tinting the world with a touch of pink while little hearts flutter down from the sky like petals. Truly befitting of its name as a cherry blossom buff!🌸

# Secondary Resources

There are several other resources worth mentioning in regards to the main Forest Island. These include **Growth** units, **Gems**, and **Pearls**. Foggy Island resources will be discussed separately.

## Growth

Growth units are earned from completing objectives in the main quest menu. These can then be used to obtain bonuses towards various aspects of gameplay, see some of the examples shown below. Growth units allocated contribute to the overall Growth Level of the main island. These upgrades become increasingly helpful in regards to resource gains and overall efficiency. You have to complete all of the current Growth level upgrades in order to proceed to the next level. Consequently, you cannot completely forgo certain upgrades to focus growth units on specific things. Growth upgrades include, but are not limited to:

* **Lower Upgrade Cost** - Percentage based upgrade cost reduction for landmarks
* **Increased Energy Generation** - Percentage based Energy generation increase for all landmarks
* **More Hearts from Animals** - Percentage based Heart collection rate increase from animals
* **Heart Dolphin Upgrade** - Percentage based increase in rewards
* **Hearts x2** - Percentage based increase in chance to receive double Hearts

## Gems

Gems are used in the Item Shop to purchase Rare Chests and Time Tickets. They can also be used in the Foggy Island Shop to buy Foggy Tokens. While gems can offer a nice little boost, they are not required to complete basic game-play objectives. You cannot directly buy animals with gems. I recommend holding a stash of ~660 gems on reserve at all times so that you can buy chests or time tickets for timely quest objective completion (if you ever find yourself in a pinch).

### Ways to Obtain Gems

1. Regular Login Rewards
2. Watching Ads (Gem Tab of the Shop)
3. Giant Clam Gift (70 gems - costs 200 Pearls)
4. Random Gem Bundle from Hatching Eggs
5. Seasonal Pass Rewards
6. Dolphin Buddies Quest Completion (100 gems per quest - 600 max)
7. Bonus from In-Game Purchases (Many of the items from the Packages Tab of the Main Shop include Gems)
8. Direct Purchase of Gems in the Shop

## Pearls

Pearls are a newly added resource in version 2.5.0 of Forest Island that come from the Giant Clam. Pearls are rewarded for watching ads or using ad coupons. You can earn a maximum of 350 pearls per day, with 10 pearls awarded per ad view. These can be collected to purchase gifts from the Giant Clam, including some limited-time/limited-quantity special rewards. The current 62 day period of rewards (as of October 30, 2023) includes the following gift items:

Some quick math for you: 350/10 = 35 ads viewed per day to collect the maximum number of daily pearls. 3500/350 = 10 days of max pearl collection to purchase the Island Fox gift. 7000/350 = 20 days of max pearl collection to obtain Baby Black Bear reward.
