From SmashWiki, the Super Smash Bros. wiki
Bomb-fest (大爆発大会, Great Explosion Contest) is the 3rd event match of the 51 event matches in Super Smash Bros. Melee. As an available character of their choice, the player must win a stock match against a team consisting of a CPU red Link and a CPU pink Samus, on Princess Peach's Castle, with no time limit. Every character starts with 1 stock. The event match contains a large number of explosive elements. Link's Bombs and Samus' Bombs are used frequently by the CPUs' AI. The selection of items that appear is limited to Bob-ombs, Motion Sensor Bombs, and Poké Balls that release only Electrode. Banzai Bills also appear as a stage hazard. The Motion Sensor Bomb trophy is awarded for clearing this event match.
