At the Shiba House, Kevin watches as Emily and Mike train. Kevin tells Emily that she needs to be more tough. Mia tells Emily about a sale at the mall where she buys an outfit that makes her look tough. Mia accidentally drops her wallet at the mall without knowing and it is found by Bulk and Spike, who attempt to return it. At the Sanzu River, Serrator tells the Nighlok Grinataur about his mission, to give humans an insatiable urge to eat, eat and eat until they “burst”. Grinataur manages to put the Rangers (save Emily) under the eating spell. Ji tries to help out the rangers with their uncontrollable hunger and thirst but to no avail. Bulk and Spike discover the Shiba House’s location from Mia’s Driver’s license and ask Mentor Ji, if they can train there. Mentor Ji puts Emily in charge of training Bulk and Spike to be Samurai which is harder than they thought. In the end, Emily destroys Grinataur on her own. When the effects disappear, the other Rangers are affected with amnesia of the period, so Emily and Mentor Ji tell them that it was the toughest day ever.
