The Barista is a dog that works at the Café. The Barista will always be in the Café to talk with the player if they choose to do so. He offers advice, hint at upcoming Perfect challenges, and, perhaps most importantly, the ability to skip stages which the player cannot clear.
His appearance is that of a small white dog with a black tail. He wears a pair of red and blue headphones, which he acquired from an unknown human who found him as a puppy. In addition to the Café, the Barista also appears in the Rhythm Heaven game "Airboarder" and the Rhythm Heaven Fever version of "Night Walk". He makes cameo appearances in the rating screens of numerous other games throughout the series as well.
