This Yo-kai visits homes asking "Any brats here?" He uses his knives to scare children. He is revered as a popular figure, so much as so that people dress up as him to scare children into being good.
In the anime, Snartle is seen trying to scare children (as he is supposed to do). His knives cause him to end up in jail so he asks Nathan to help him. Nathan calls out Hanako-San to help him too reinvent his image. Unfortunately once he becomes rich and famous, he and Hanako are caught for evading taxes, something neither of them knew about.
How to be Friends With Him
Once your yo-kai team is strong enough, you'll want to cross the street at crosswalks without pressing the button on purpose so Snartle will appear and fight you. Throw him his favorite food and it's business as usual to befriend him, However, The Snartle that appears at crosswalks is extremely powerfull, and the higher your watch rank, the stronger this Snartle's attacks are. You can also go to the Tranquility Apartments at Shopper's Row and befriend him like any other Yo-Kai. I prefer you use Marbled Beef.
He is a small humanoid like figure with a big ogre mask for a head. He has long yellow hair and large brown horns. His face is blue and white and he has a large snarl. He wears purple armour with green clothes underneath. He carries around two large metal knives.
Snartle is rather gentle for being the Yo-Kai of terrorizing children.
In episode 63 he makes his first appearance, finding he is not capable of scaring children anymore without being arrested, he seeks Nathan's help. Nathan calls the Yo-Kai Hanako-san and she helps Snartle reinvent himself. She becomes his producer and the two gain their way to fame.
Snartle is based on a creature of Japanese folk-lore. His Japanese name, Namahage is also a traditional custom where men of villages will dress up in large ogre masks and straw and barge into houses in their village to scare and convince people and children to be good to their parents and respect authority, as well as work and study hard.
Snartle is a mix of the words Snarl and Startle.
Namahage is a the Japanese creature from folklore the character is based on.
