Mountain Pig Castle

Before retrieving the fourth egg
Wizpig flies in front of the birds then flies back to his position. Prince Porky also jumps into his position and is ready to defeat the birds together with  Wizpig.

After retrieving the fourth egg
Wiz Pig and  Prince Porky  has been defeated and this time there's no way for them to run as the birds are standing on their way. The birds then collect the fourth egg, not realizing that Wiz Pig  and  Prince Porky  are escaping from Mountain Pig Castle. Red goes up to the top of the castle and shout, demanding the two pigs to give the fifth egg back, making both Wiz Pig  and  Prince Porky  start to get angry as well.

When they look at the Chronicle Cave, another light turns on for rescuing the fourth egg. Wiz Pig runs away and leaves the birds behind. Prince Porky also jumps onto his cloud, but that made  Wiz Pig  frightened and lose control of the magic cloud. They bump onto a Royal Guard standing next to King Pig's Castle, making him fall and die. Luckily, they manage to stop the cloud when it almost crashes King Pig. King Pig asks them about the five eggs he has commended. The pigs turn around to see the cloud having only one egg. The King sobs in disappointment. But one egg is better than none, so Wiz Pig  puts the fifth egg on the top of King Pig's Castle.

Strategy 1
Choose Red in Samurai, Matilda in Druid and Bomb in Cannoneer. In all waves, heal with Matilda when the birds' healths are not full, otherwise, attack with her. Then attack with the others. The order of the attacking targets are:

Wave 1: Chieftain and then the Pig Guards

Wave 2: Frostpig and then the Snow Pigs

Wave 3: Ice Shaman first, then the Frostpig

Wave 4: Royal Bombs only.

Wave 5: Prince Porky and then Wiz Pig (don't attack the Trap Bomb except when Wiz Pig's Dark Energy ability is active)

Also, at wave 5, use Red's secondary skill on the bird which have the lowest current health when Wiz Pig is about to attack. Repeat this over until you win or lose.

Don't use the Rage Chili on wave 1. Use it on wave 2 on Red (once only) and wave 3 on Red again when the Rage Chili is full for the first time but from the second time and so on, use it for Matilda. Also, watch out for Ice Shaman for his Mimic power. But don't worry, after you defeat the Ice Shaman, give the Rage Chili to Matilda and you can heal again. At the fourth wave, don't use the Rage Chili to Bomb to destroy all the bombs. Attack with the birds and destroy all the Royal Bombs in 2 turns. Don't worry about the Trap Bombs on both wave 4 and wave 5 because they only deal 4 damage. At wave 5, when the Rage Chili is full, wait until Wiz Pig attack. Then, after he attack, use it for Matilda when Prince Porky is not dead yet. When there're only Wiz Pig left, wait until the Rage Chili if full and then wait until Wiz Pig's Dark Energy power is expired, use it on Red.

Strategy 2
Choose Chuck in Rainbird, Matilda in Druid, and The Blues in Rogues. Make sure the birds have their mastery ranks level 3-5. Level rank must be 11.

Wave 1 - First attack with the Chieftain with all birds. Then heal the most hurt bird (both with Matilda and Chuck). Then use Cupcake Trap on the bird with highest health. Heal the bird will Cupcake Trap. Then repeat until you defeat all the pigs.

Wave 2 - Attack the Frost Pig first with all birds. Then heal the most hurt bird. Apply Cupcake Trap to bird with highest health. Remember to heal that bird. Repeat this until pigs are defeated. If chili is full, give it to Matilda if health is low. Give it to Chuck when birds' health are high.

Wave 3 - Attack the Ice Shaman first. Then heal. Give the chili to Chuck when full (3 times only). Give it to Matilda when health is low (unlimited). Repeat until you defeat the pigs.

Wave 4 - Only attack the Royal Bombs. Ignore the Trap Bombs. Heal if you didn't defeat one of the Royal Bombs. Heal with all the potions you have (heal them until birds have full health for the next wave).

Wave 5 - As what I said in Wave 4, birds' health must be full when you enter. Attack Wizpig first, then give the chili to Chuck when full. Give to Matilda when health is low. Keep repeating until Wizpig is defeated. Attack Prince Porky with all birds. Then heal The Blues with Chuck, Matilda and potions. Apply Cupcake Trap to themselves. Then heal when Porky attacked. Then attack until he's defeated. Porky may be defeated after a few times he attacked the Blues.

In Summary
This battle can be quite a challenge, as Wizpig can make enemies that attack him take damage. Prince Porky will use Tit For Tat to work in his favour.
