Inspired by the Joker of Batman fame. Also inspired by the awesome and totally tubular 1980’s. And neon, also inspired by neon.
Even Mr. Freeze from Batman the Animated Series enjoys a good show tune. He saw Disney’s Frozen 10 times opening weekend. He has the Frozen soundtrack and everything. Building Olaf the snowman all across Gotham city was a natural progression. I’m sure even Batman and Robin will join in.
