Yo-kai Watch Animation
Count Cavity appears near the end of The High-Fright Zone, when it is revealed he was the cause of Nate's cavity and the subsequent trip to the dentist complete with all the terrors he got from a Blazion-possessed dentist way back in EP006. Upon realizing this, Nate uses Whisper to send Count Cavity flying.
Count Cavity can be freed from the Crank-a-kai with a Blue coin, Five-Star Coin or Special Coin, and he can be found in the Infinite Tunnel 7,000+ yards in. Additionally, he appears randomly after brushing your teeth.
As of the Oni Evolution Update, he can also be freed from the Happy-Go-Lucky Crank-a-kai.
