Western Bamboo Forest

Strategy 1
First, play all the other levels until you rescued all birds. Then get back here and buy Matilda's Princess and choose Red in Samurai, Matilda in Princess and Bomb in Pirate. Heal with Matilda if a bird's health is not full and if otherwise, attack with her. Then attack with the others. Remember to use Red's secondary skill on the bird whoever that the Ronin choose to attack, if not, he will attack you +700 damage. Use the Rage Chili on Red when it is full (may not be possible, so it is recommended to make some veggie cakes). Repeat this over until you win or either lose.

In Summary

 * Ronin will deal massive damage to you, but it decreases everytime the Rage Chili is filled up. So always use your Rage Chili before he unleashes his devastating attack.
 * Ronin is so strong that you must sacrifice your one or two birds in order to defeat him using Cupcake Trap from Blues' Rogues.
