About the Holiday
Today’s holiday encompasses so much more than keeping clean. Sure, a soaking in a tub of warm water is necessary and relaxing, but did you know that a bath is responsible for a mathematical and a linguistic discovery? The story goes that on June 14th in the year 287 BCE, Greek mathematician, scientist, and scholar Archimedes, noticed that when he stepped into the bathtub, the water rose. He realized then that by submerging an object in water, he could accurately find its volume by measuring the amount of water displaced. Unable to contain his excitement over this discovery, Archimedes leaped out of the bathtub and ran naked through the streets of Syracuse, Greece yelling “Eureka, Eureka!” Thus, both a scientific principle and a new word were born! To celebrate today, take some time for yourself and indulge in a nice long soak!
Naughty Ninja Takes a Bath
Written by Todd Tarpley | Illustrated by Vin Vogel
Naughty Ninja had been training in the jungle when his rumbling stomach told him it was time to go home. As he stepped in the door, he announced that he needed food. But Naughty Ninja aka Will “was covered with river mud, smelly leaves, and beetle dung. Flies buzzed around him.” His mom and dad told him he needed to take a bath before he had his “ninja nuggets.”

Will’s dad filled the tub and calmly reminded him not to say “‘Ninja to the rescue’” because whenever he did bad things happened. But Naughty didn’t hear. He was focused on the flies that were now swarming around his dad. He recognized them as “wild, poisonous flies from the jungle.” His dad saw the gleam in his eyes and begged him not to say those dreaded words.
But they were already leaving Naughty Ninja’s mouth, and his foot was already coming up to kick those flies. Unfortunately, he kicked his dad instead. Dad fell backward into the tub of water. Naughty Ninja was sure a fierce alligator had dragged his dad into the tub. Calling out his signature phrase, Naughty Ninja leaped into the air and rescued his dad. Of course, he also caused a tidal wave of water to fill the bathroom. He was sure his dad was okay now, but Dad said he was ‘not better.’ Naughty Ninja thought about this. “It could only mean one thing…invading samurai warriors!” In on smooth move, Naughty Ninja picked up the bubble bath, soared into the air, and poured it into the tub. In a moment, clouds of bubbles filled the room. Naughty Ninja yelled for his dad to run.

As water and bubbles, bath toys and toothbrushes flowed out of the bathroom, Naughty Ninja bounded across the bathroom and out the door. Ninja Dad gave chase with an armload of towels. But Dad slipped and slid on a towel across the room and back again. “Naughty Ninja thought that looked like fun.” He grabbed a towel and slid loop-de-loops around the floor, walls, and ceiling. By this time even Ninja Dad was having fun.
They came to a halt in front of Mom, who wanted to know what they were doing. “Naughty Ninja and Dad stopped and slowly pointed at each other.” Mom didn’t care who started it or how it had happened. She was just thrilled with how clean the house looked. Dad smiled at Will. It was just another successful Ninja rescue.

Todd Tarpley’s madcap ninja adventure will thrill kids who play hard and have active imaginations. His funny description of Naughty Ninja’s dire need for a bath segues naturally into the slapstick comedy to come. Ninja Dad’s wary warning ramps up the suspense, and readers will be eagerly anticipating Naughty Ninja’s catch phrase to see what “bad things” happen. Tarpley’s disconnect between Naughty Ninja’s thought process and his dad’s desires to get him in the tub create moments that will have appreciative kids laughing out loud. As Dad embraces the slip-sliding fun and Mom thanks them for cleaning the house, readers will be happy to adventure with this Ninja Family again and again.
Vin Vogel’s humorous, action-packed illustrations depict all the fun of Naughty Ninja’s imagination with clever details and a deft eye for scenes that make kids giggle. Flailing arms, heroic leaps, and air-born kicks are all part of Naughty Ninja’s repertoire, and his ninja outfit (which includes a black hoodie with the size tag sticking out and one untied sneaker) is inspired. Readers will enjoy pointing out the flies, bath toys, and bath accessories that become unwitting stars of Naughty Ninja’s daring rescue.
Sure to be a favorite of Ninja-loving kids and fun-loving adults, Naughty Ninja Takes a Bath would be an often-asked-for addition to home, school, and public library collections.
