As soon as the invasion started, Numbuh 3 and Numbuh 4 were assigned to help protect the Wilds from Fuse's minions. Numbuh 4 had wanted to leave and join the battle in Downtown, but after Numbuh 3 was nearly killed in a Fusion Spawn attack raid he realized he was needed there. Ed managed to escape here from May Kanker's pursuit and actually likes it there. He now proclaims himself King of the Jungle. When the invasion began, Coco got scared and fled into the Wilds and Mac went to find her; eventually both of them managed to hide here. Due to Coco's power to use her eggs against Fuse, Fuse has appointed Fusion Mac, Fusion Numbuh 4, and Fusion Toiletnator to try to capture or destroy her at all costs. They periodically attack Coco and the fortress to carry out their plans.
