Kai thanked Sensei Wu for saving him but demanded to know what had just occurred Sensei Wu explained that the Retreating to the Skull Truck with his fellow generals, Samukai told Kruncha to 'take the girl!' In response, Kruncha fired the truck's bone hand, snatching Nya as the skeletons retreated to the Underworld. After exchanging a few taunts, Samukai threw his daggers at a nearby water tower, forcing Sensei Wu to save Kai before the structure collapsed. Sensei Wu intervened before Samukai could deliver the finishing blow, knocking the Skulkin General around with a strange golden tornado of energy.

With the soldiers defeated, Kai challenged Samukai himself, but the four-armed skeleton quickly disarmed him and knocked him to the ground. After a scuffle with each other, the Generals found what they sought on the back of the shop's sign-a large piece of parchment. Meanwhile, unnoticed, Kruncha and Nuckal snuck into the store, searching for something. Wielding a bamboo staff, Nya joined in-despite Kai's warnings-and the two of them managed to fend off the Skulkin. Upon seeing the approaching skeletons, Nya wondered aloud what was going on, but Kai simply told her to stay in the shop while he confronted the invaders.ĭonning armor and taking up a sword, he challenged the Skulkin forces, doing surprisingly well despite the undead warriors' physical and numerical advantages. Samukai ordered his troops to attack, and the Skull Truck raced towards the blacksmith shop, surrounded by the Skull Motorbikes. Atop the Skull Truck, Nuckal begged the Skulkin leader, Samukai, to let him lead the attack, claiming that he was ' dying to go down there.' His friend, Kruncha, irritably reminded him that they were already dead. Moments later, a dark cloud spread over Ignacia, signaling the arrival of the Skulkin. Kai rudely told him that their shop was the 'Four Weapons,' not 'for browsing,' and Sensei Wu left. At Four Weapons Blacksmith, siblings Kai and Nya were busy crafting weapons when Sensei Wu came down the road and began to browse around their shop.
