After defeating Wizpig in space in Adventure 2 (and possible after the normal adventure; I can't quite remember as it's been some time since I've played), when the credits roll, there are times given for each of the levels. These times are extremely fast, and I remember only ever being able to beat one of them after a hundred tries or so.
What is the significance of these times? They are shown with no context, just a level-name and a time. Does anything special happen if you manage to beat them all?
