Shroob missile

"It's a Shroob missile, and it's headed straight for us!"

- Koopa Troopa

A Shroob missile is a weapon used by the Shroobs in Mario & Luigi: Partners in Time. It is summoned from the Shroob Castle to target the protagonists in the Koopa Cruiser. Due to Baby Bowser being out of spiked balls, the Koopa Cruiser gets struck by it and crashes into Baby Bowser's Castle.
