In an attempt to head towards their ancestral home of Pennsylvania (since their parents are pencils), the Warners end up at the estate of Count Dracula in Transylvania.
The title is a parody of the chorus of "Happy Wanderer", "Val-de-ree, val-de-rah".
In the end, the Warners end up in Tasmania and meet the Tasmanian Devil. The Taz-Mania theme music is heard in the background during his appearance.
In the beginning, the Warners burrow to Transylvania while Yakko looks at a map and says, "I know we're not rabbits, but it's a Warner Bros. tradition." This is a reference to the way Bugs Bunny traveled, who would always end up in somewhere other than his destination just because he took a wrong "toin at Albukoikee."
Dot's full name, Princess Angelina Contessa Louisa Francesca Banana Fana Bo Besca, is revealed in this episode.
This was John P. McCann's first script for Animaniacs. It led to his being hired to the show as a series writer.
The fourth wall is broken in this episode, when Yakko says to the viewer "We're not that stupid, we just know the plot."
When Dot introduces herself, you can hear Mindy's theme in the background.
When Dracula introduces himself, Yakko asks 'Didn't you used to teach math on Sesame Street?', mistaking him for Count von Count from the hit PBS Kids/HBO series.
The voice of Count Dracula is Dan Castellaneta, who voices Homer Simpson on The Simpsons and Grandpa Phil from Hey Arnold.
Yakko mentions Batman.
