Despite its cute appearance, the scary cavity bacteria are very active!
Everything you need to know about cavities in one book!

The pumpkin candy that So-maek's older sister fed him to wake him up from hunger ended up sticking to his teeth.
The tongue and the mouth guards inside the mouth dissolve the pumpkin candy with saliva with the help of the salivary glands, but they do not notice the existence of the pumpkin candy hidden between the teeth.
Then, a few months later, while eating, Somaek feels a sharp pain and is shocked to hear that he has a cavity and needs to go to the dentist. How did the cavity-causing bacteria invade Somaek's teeth? Can Somaek and his teeth fend off the terrifying cavity-causing bacteria and return to good health?

Based on the popular video "A Day in the Life of Human Friends," which has approximately 57.8 million views, the "Human Friends of the SomackGuffin" series features original stories and new human characters in each volume.
In Volume 4, not only the bacteria that cause cavities, but also the various organs in the mouth and throat appear as characters with their own unique characteristics, providing a variety of knowledge about the human body in a friendly manner.
'Draw My Teeth', which records the results of direct observation of teeth, and word puzzles made up of words from the book add to the fun and educational aspect.


Linking with elementary science curriculum is essential
Fun and knowledge about the human body, caught in a medical gag comic!

This book contains key information on 'The Structure and Function of Our Body', a 6th grade, 2nd semester elementary science course.
You can naturally learn about the nose through which you breathe, the mouth through which you eat and breathe, the path through which air and food enter, and what cavities are.
Not only that, but even the content learned in the human body section of middle and high school science textbooks can be easily learned through comics.
This is because it incorporates information about the types of salivary glands, the functions of saliva, the structure of teeth, baby and permanent teeth, and cavities into cute characters and an interesting story.

Knowledge that could not be conveyed through the comics is intensively covered in the information page, 'Human Body Friends Exploration'.
Interesting topics like "Does less saliva cause bad breath?" and "Teeth are shaped differently for everyone!" are explained with friendly explanations and easy-to-understand illustrations, making it fun and educational.
To avoid any misunderstandings due to the cartoonish expressions, we have included a 'True or False' corner to provide accurate information.
