Limestone Lagoon - 1

How to win this stage
Choose the following birds and classes:
 * Chuck as Lightning Bird.
 * Bomb as Pirate.
 * Matilda as Cleric.

Now follow the strategy below:

Wave 1
There is only 1 Pirate. Get all the birds to attack and defeat him.

Wave 2
Defeat the pigs in the order below:
 * 1) Matey
 * 2) Pirate
 * 3) Pirate Veteran

Now do the following:
 * Make sure both Healing Shield and Arrr! are active. If not, use them first.
 * If the rage Chili is full:
 * If any birds have less than 50% health, then use the Rage Chili on Cleric for emergency healing.
 * Otherwise, use it on Lightning Bird.

Wave 3
Defeat the pigs in the order below:
 * 1) Matey
 * 2) Stick Pigs
 * 3) Big Pirate

Again, do the following:
 * Make sure both Healing Shield and Arrr! are active. If not, use them first.
 * If the rage Chili is full:
 * If any birds have less than 50% health, then use the Rage Chili on Cleric for emergency healing.
 * Otherwise, use it on Lightning Bird.

This is the most dangerous wave due to Big Pirate doing massive damage on all birds. The Healing Shield helps as it will reduce the total damage taken by 45% but it can still hurt a lot.

One last thing, do not be afraid to use healing items if you are in a desperate situation.
