Cookie's Bustle: Mysterious Bombo World[a] is a 1999 Japanese point-and-click adventure game created by Keisuke Harigai and published by Rodik[2] on Windows and Mac OS.

A hundred years prior to the events of the game, aliens crash-landed on Bombo World, a fictional island country in the South Pacific.

After arriving in Bombo World, which is still in a state of political unrest, Cookie plans on meeting her grandmother, Nancy Blair (voiced by Miyuki Ichijo).

A novelist named Unmo Sable (voiced by Shigeru Shibuya [ja]) tells Cookie that she must have a strong heart before she is allowed to pass.

After lifting the cross on Simpson's grave, his ghost tells her the location of the N66 bomb to pass it on to his allies inside Derocity.

After winning the gold medal at the Bombo World Olympics, the goddess notifies Cookie that the aliens have captured Dr.

Right dies, he informs her that the aliens plan on destroying Earth and the only way to stop the bomb is with the passcode "Nancy" — named after Cookie's grandmother.

Cookie also frees a singer named Jessica (voiced by Satomi Kōrogi), but the former is arrested by the police and is trapped in prison for three days until Mu saves her.

Cookie disarms the bomb in time, but the aliens approach her and reveal that they came to Earth and held the Bombo World Olympics to observe humanity.
