It is goofy, but in a kind of sinister, mocking way...very much like Shostakovich (or Elfman, who was inspired by him).
He was the de facto "official composer" representing Russia during WWII and the Cold War, when in fact he detested Stalin and the way they pressured him to change his music to suit their desires, or in some cases outright censored him. They used his music as propaganda. He would respond by inserting bumbling, circus-like music in his scores that was literally meant to mock Stalin and the Bolsheviks (or Khruschev). Or he would write over-the-top optimism, like his "Festive Overture," mocking the esprit de corps of the Communists.
I'm not saying I'm 100% sure this is real, but all along I have been imagining something like this being in the score...a nod to the great Russian composer of the Cold War, Shostakovich. In that sense, it's very fitting.
