I don't have either cable nor satellite, so I don't have Cartoon Network, so I can't see the show. From what I have seen, there's a small music video in each episode. One of them, called "We are in Love" is a love song about Lola and Bugs Bunny. Here's a scene where Lola's on the phone, er, headphones.
Found this on Cartoon Network's website.
