Madatascar Island's geography is similar to the structure of Univeral Studios Japan's WaterWorld stage. Not much is known about it.
Each year, the residents of Madatascar Island host an annual festival. The festival features fireworks displays created by Volg and Flora, but while the DX Marines were in power, fireworks were banned. The festival proceeded as normal after the island's liberation.
Volg and Flora were creating a special fireworks display the latter designed when the DX Marines came to Madatascar Island and seized control of it. The group banned all fireworks and demanded absolute obedience from the island's citizens.

The Straw Hat Pirates came to Madatascar Island, and a fake of Crocodile launched a sandstorm at them, separating them. Away from his crew, Luffy encountered Volg and Flora, who explained the island's situation with the DX Marines, and Luffy vowed to help them. A fake of Boa Hancock confronted the crew and petrified Sanji, and a fake Law also appeared under the DX Marines. Luffy returned to his crew and fought Smash and Bildy while the rest of the crew fought their Seven Generals. The real Law appeared and confused the crew, and Bildy revealed his powers. Caesar Clown, who had been captured by the Straw Hat Pirates, appeared, and Bildy created a fake of Oars. Mihawk arrived and cut Caesar's Shinokuni in half. Luffy defeated Smash with Gomu Gomu no Grizzly Magnum, and the island was freed, allowing the annual festival and schedule fireworks to proceed.
