PaRappa

PaRappa Rappa (パラッパ Parappa) alias PaRappa the Rapper (or simply PaRappa), is a rapping dog and the titular protagonist of the video game franchise of the same name. His adventures usually lead to difficult situations which he counters with his catchphrase, "I gotta believe!" and pulls through.

Trivia

 * Despite the name of the anime, Parappa only raps once in the final episode. It was in English and was a borrowed song from the games.
