Can't retrieve a song

After looking through the Funday Pawpets episode list, I found a specific parody song I was looking for: A parody of The Monkees' "I'm a Believer" called "I'm a Retriever." Unfortunately, the artist's name was not listed and it's not coming up when I search the lyrics. There are other parodies with this title, but they're not this specific one. I've tried to Shazam the song, and also looked on YouTube and Dr. Demento's site. No luck. I later thought the song was by Trout Fishing in America, but I don't see it on any of their albums either.

Only 29 days until my singles cruise reunion in "Pizza-Baggu!"
