The Yello Dello
From Homestar Runner Wiki
The Yello Dello is one hot bird. The Yello Dello is the rarest and most beautiful bird in the Yello Dello cartoon, and can be found on a tall mountain in Potamia, a far off land. Homestar Runner, Pom Pom, and Strong Sad embark on a quest to acquire it and give it to Marzipan for her birthday.
Although it has a male voice, apparently it's a female, as Marzipan and Strong Sad call it a "she".
