Wai Wai World 2: SOS!! Parsley Jō

Wai Wai World 2: SOS!! Parsley Jō (ワイワイワールド2 SOS!!パセリ城) is a 1991 Famicom platform game released only in Japan by Konami. It is a sequel to Konami Wai Wai World, and stars various Konami characters. It was also re-released for the Wii U Virtual Console on September 2, 2015 in Japan.

Gameplay
The player begins the game by choosing one of four character groups which consist of three different Konami characters. Most of the levels are spoofs of various different levels from Konami games. The gameplay is mostly like a straightforward platform game, similar to Contra. In these levels, the player starts off with the main character Rickle (or Rikkuru), who by collecting a special power-up, can transform temporarily into one of the three different characters the player chose at the beginning of the game. There are also space shooter, driving, and puzzle levels. After certain levels the player can choose different paths which consist of different stages.

Plot
Peaceful times were reigning in Wai Wai World, when suddenly a great wizard by the name of Warūmon emerged from the darkness and swiftly conquered the land. In response, Dr. Cinnamon, who escaped the attack for being away on a sightseeing trip, created a super robot named "Rickle" by using his secretly developed "Konami Hero Transformation Circuit" and sent him forth to defeat Warūmon.

When Warūmon learned of Cinnamon's plan, he kidnapped Wai Wai World's Herb Princess and took her away to his base in outer space, known as "Parsley Castle". There, he revived villains that had been previously defeated by former Konami heroes and sent them over to stop Rickle.
