The Patapons have decided to build a fort in Dodon Basin, to stop the repetitive Zigotons' attacks. Meden and some Kibapons will transport a huge Tender Meat to Dodon Basin and they need some escort (obviously, this means your army). You'll be dealing with some waves of Zigotons. Just do the same what you did to the previous missions- Kill the Zigotons! The 3rd and the 4th wave (especially the 4th wave) will be the hardest.
