Chirpster

is a Boss Yo-kai, and the Hidden Boss Yo-kai of the Old Mansion, unlocked by performing some Requests that appear in the Old Mansion. His Yo-kai Medallium entry states, "If you hear music coming from an old, abandoned mansion, this Yo-kai is likely partying there. If you stumble in, you may be dancing 'til dawn!"

Appearance
He is a giant bird Yo-Kai with clothing, a fan in his hand, his right arm on a mini table, and he is sitting on a pillow.

Abilities and Powers
He has two box Yo-kai that may lick your Yo-kai, which will make them numb and be unable to move as a result. They may also "Lickety Lick" Chirpster, which will heal him.

In his move, Which Will it Be?, he chooses one of his box Yo-kai and you will have to pick one. If you pick the wrong one, either all of your battling Yo-kai will get hurt, or it heals more than 300 points of Chirpster's health.

He has the power to confuse one of your Yo-kai by using his "Chirpster Lovin'" in order to become infatuated with him.

His technique is Gusty Winds.
