In the US version, the trophy is called Bullet Bill with the following description:
Bullet Bills are shot out of cannons and fly on straight paths. In great numbers they're a nightmare; while Mario can stop most with a single jump, the rare giant one is much tougher to avoid. In Super Smash Bros. Melee, all Bullet Bills are extra large. They burrow into Princess Peach's castle and then detonate with immense power.
