Mud Zombie

Mud Zombie: The summer type Makamou that resemble a mud-based humanoid with the features of rice plants, & an apple snail, dragging people into the muddy water it resides it. A Mud Zombie appeared in a nearby village near where Echo Demon & Roaring Demon were training. The Makamou revealed itself to save its Prince, but has begun to multiply itself. While Roaring Demon & Majestic Breath Demon use Taiko gear to deal with most of the copies, Echo Demon eventually enters Crimson mode & defeats the original with Scorching True Crimson form.

Prince & Princess
First of the Summer Prince/Princess created by the White Puppet, native-sounding in personality though their airheadness belittles their true maleficent nature. They chant "Ken, Ken, Pa" when approaching their victims, spit mud from their mouths at the victims & knocking them into the muddy water for the Mud Zombie to grab & nearly drown them before eating them. They crossed paths with Echo Demon & Roaring Demon, using a hit-&-run method of attack that ends with the Princess destroyed by Echo Demon's Raging Fire Bullet. The Prince escaped thanks to his child, overseeing the multiplication process until the Oni battled the Mud Zombie horde, with Roaring Demon taking out the Prince with Lightning Strike Fist.
