Godzilla vs. Y2K Bug
Whilst having a party for the new millennium on the Calico, the crew encounters the Y2K Bug. It flies above the ship roaring down at them until Pete announces its presence to which the monster says "Actually, I prefer Millennium Bug" before continuing to roar. Fearing that the monster will wreak havoc on computer-bearing devices, the crew attempt to call on Godzilla for help. However, as Carl attempts to use the Godzilla Signal, it begins sparking with no sign of Godzilla. Quinn concludes that Carl must not have updated the device's embedded microchips and the short concludes. It is unknown what happened to the Y2K Bug after the events of this short, however it is assumed the monster was somehow defeated.

Abilities
According to Quinn, the Y2K Bug has the capabilities to wreak havoc on anything which uses a computer, listing examples such as crashing the stock market and causing power grids to fail, although these events are never shown. The Y2K Bug also possesses the ability to communicate using human speech, as well as producing roars.
