Desert Pig Castle

Before Retrieving Second Egg
 Prince Porky  was about to attack the Birds but he was scared because he was too small and weak for the birds, and so, he calls  WizPig  again. The birds were scared again but not too much, he was just bigger than ever. The birds were very crossed.

After Retrieving Second Egg
After the birds got the second Egg, WizPig and Prince Porky go tip-toed outside the castle and they ran away without any notice. But after that, Red comes out and he sees them. For the second egg, the second light at the Chronicle Cave turns on, and that would mean they have retrieved the second egg. Then, Prince Porky goes far, far away by his ship and WizPig flies away with the other three Eggs. Then, WizPig puts the third egg  on top of Star Reef Castle, which he thinks that the birds will definitely cannot beat him.

Wave 5
Summoned:

Either 2 Royal Bombs, 2 Trap Bombs or 1 Royal Bomb and 1 Trap Bomb. Both bombs' stats are shown below.

Note: If Prince Porky is defeated, the stage ends even if there are any Trap Bombs or Royal Bombs remaining.

Strategy
Warning #1: Do not use the Rage Chili on the first wave, second wave or the fourth wave. Only use the Rage Chili in the third wave for The Blues to stun and deal a lot of damage to a pig and the fifth wave to them again to stun Prince Porky.

Warning #2: Be careful. The Pyropig may activate "Fire Power", which can increase all allies' attack power by 30% for two turns while Lightning Pig is charging his attack. Use The Blues in Tricksters so you can dispel the Lightning Pig. (however, if there is only Pryopig left and he uses his secondary skill, you do not have to worry since his skill wears off before he has a chance to unleash his charged attack).

Warning #3: Be careful. The Lightning Pig may activate "Fully Charged", which all attackers receive 51 damage per attack for two turns. Use The Blues in Tricksters so you can dispel either the Lightning Pig or the Pyropig.

Warning #4: Be careful. Prince Porky may activate "Tit for Tat", which will increase dealt and taken damage by 25% for three turns. Use The Blues in Tricksters so you can remove the attack boost from Prince Porky.

Warning #5: Be careful. Corporal may activate Lick on either himself, or the Pig Guards for 359 health after charging for 2 turns. Defeat him (or at least the Pig Guards) before he does that.

Warning #6: Be careful. The Bird Catchers may have a 5% chance to stun you for one turn. Use Matilda's rage ability, so you can not only heal the bird who is stunned, but also remove all harmful effects on target. (Tricksters's secondary skill can also be used)

Warning #7: Be careful. Prince Porky has the dodging power, which he would ignore damage greater than 63. (as of v1.1.7, he now treat all damage greater than 63 as 63 so it will be easier to take him down)

Warning #8: Be careful. At wave two, some of the pigs may stun you, better yet, they will get your birds straight out of the game and out of health, and if you do not revive birds within the next 5 seconds, your opponents will win by default.

You can choose Red in Samurai, Matilda in Druid The Blues in Tricksters. First, heal with Matilda, and then second, attack with the Birds. At the fifth wave, if there are no bombs or if the bombs are Trap Bombs only, increase the attack power of all birds by The Blues when they have expired (only increase the power by The Blues when the Rage Chili is not full, otherwise, give the Rage Chili to The Blues for him to stun Prince Porky), then use Matilda and Red to attack Prince Porky. If one of the Birds' health is under 50% health, heal them by Matilda instead. If there are several bombs and there is at least 1 Royal Bomb, use Red and The Blues to attack the bombs and don't attack the Trap Bomb. If there is only a Trap Bomb on the battlefield, use The Blues' secondary skill. Repeat this over until you win or lose.

In Summary
Even with the Blues' high damage and Red's impressive defense, it won't take long for the pigs to defeat your birds. If only there was a Rage Ability that heals AND removes all harmful effects.
