When sitting on his Chinese Lantern, there is a rare chance that Gizmo will sing Frank Sinatra's "New York, New York". This is an homage to a scene towards the end of the film "Gremlins II: The New Batch", where the near-entirety of the film's Gremlins sing the same song as a big musical number with the Brain Gremlin leading the pack and providing the vocals.
