Not much is known about him, but he is a singer similar to Justin Bieber and even pronounces "swag" wrong. He is shown as a good singer also, much to Sam and Daisy's delight and Cat's dismay. Cat then accidentally fires a turkey at him out of the turkey cannon Dice brought over which knocks him out for a few minutes.
He likes parodying Justin Bieber for a living as shown as he pretended to be Justin Bieber after Sam paid him.
Sam paid him to perform for the three kids she and Cat were babysitting so they would pick her as their favorite babysitter.
Daisy loves Justin Fever as she loves Justin Bieber.
- Unlike what some fans could think, he isn't a parody of Justin Bieber, as Bieber has been mentioned in some episodes, including the one in which he appears.
- He pronounces the word "swag" wrong.
