Here's an interesting Metroid
cameo. Galactic Pinball, Samus Mini-game: Hit the ball
into the top-right part of the Cosmic board with the bumpers.
Start the "Bumper Clash" sequence and hit all the
bumpers to start a Samus mini-game. The S symbol from Super
Metroid will appear in place of the bumpers, and the phrase
"Let's Go, Samus" will be spoken. The ball will
transform into the Samus' ship, with the goal of shooting
Metroids and other targets while the Super Metroid theme is
played. Thanks to Ferry Groenendijk of Virtual-Boy.net
for this description and the screenshots.
During the bonus game in MC,
Luigi, Princess (behind the flag on the left),Yoshi (not pictured),
and a lot of mushroom people can be seen sitting in the crowd.
Yoshi is on the right side of the stands. Thanks to Ferry
