Archived Kimimaru4000 video from YouTube. Original description mostly intact:

This is a video of me completing the Mecha Bowser Mayhem minigame in 47:28 with Yoshi on the Titanium Frame difficulty in Mario Power Tennis. Shorter and less powerful characters often do worse on this minigame because they can't hit the Bullet Bills that come after them as easily as tall characters, and they also can't hit the Bullet Bills back at Mecha Bowser as soon as he shoots them out.

Time: 47:28 (47 seconds, 28 hundredths of a second) (In-game)

I'll admit it; it takes mostly luck to do very well in this minigame, mainly because Mecha Bowser's movements and the chance of a Star appearing are random. The key to doing well is to manipulate Mecha Bowser to shoot a lot of Bullet Bills, which can then be hit back at him.

As shown in the video, this time can be improved. If I had hit those 2 Bullet Bills at the end back at Mecha Bowser, I would have gotten at least 46 seconds.

Please note that this is the Gamecube version of this game. I'm not sure if there are any differences between this version and the Wii version.

Enjoy!
