The Farthest Edge of Space
From the Super Mario Wiki, the Mario encyclopedia
In the story's prologue, Dribble and Spitz are driving their taxi across space, looking for customers. Suddenly, the Space Gangs fire a laser at the taxi, causing Dribble to worry. Spitz reassures him, saying that they need to stay cool. The UFOs then fire another laser, which damages their taxi. Spitz becomes angry and tells Dribble to prepare the Octoblazooka, which they use to fight back against the Space Gangs.
In the story's epilogue, after the Space Gangs have been defeated, Spitz asks how many are left. Dribble replies that there are none remaining, and Spitz accounts the victory to his calmness, while Dribble mentions that he just wants to leave.
