Adventure Island II is a side-scrolling platform game developed by Now Production and published by Hudson Soft that was released for the Nintendo Entertainment System in 1991. It is the sequel to Adventure Island and the second game in the series for the NES. While the first game was an adaptation of Westone's Wonder Boy arcade game, Adventure Island II is an entirely original work, as were all the subsequent Adventure Island games.
Princess Leilani may be safe, but her sister, the sweet and beautiful Tina, has just been kidnapped by the Evil Witch Doctor's persistent followers. Eight perilous islands are in control of the various monster minions, although four friendly dinosaurs will gladly ally themselves with those willing to brave the islands' dangers and defeat their common oppressors.
