Jango's Dance Carnival is an animated short shown before the 2nd One Piece animated movie, Clockwork Island Adventure, taking place sometime before the Warship Island Arc, as the Straw Hats have not yet met Vivi, and Jango is still a pirate during this time. The song featured called "Ready!" by Folder 5 (who also did the second opening theme of the series "Believe").
The featurette sees the Straw Hats arriving on Mirrorball Island, which has a huge disco ball hovering over it. Unknown to them, Jango is also in the town at a local bar. However he is spotted by a group of Marines and a chase ensues. In the midst of the chase one of the Marines spots Luffy, forcing him and his crew to run for it as well. The crew falls off a building, forcing Luffy to use Gomu Gomu no Fusen, hitting the giant disco ball and causing it to swing. Jango ends up on top of a dance platform and in desperation, uses his hypnosis to make the people of the island dance. Everyone, including the Straw Hats and the Marines, are caught up in the frenzy and dance the night away, destroying the island in the process. The Straw Hats manage to escape albeit wearily, but realize Luffy is not with them. He and Jango are still on the disco ball floating in the ocean and still dancing as the featurette closes, wondering why they are the only people still hypnotized.
