You have a chance to win the Entei trophy in this match. Like the previous Trophy Tussle, you have 3 minutes to defeat 3 other characters that have 2 stocks each. Most of the time two characters will fight you while one remains near the edge. Use items and smash attack to defeat your opponents. Once you get rid of the two that fight you, then you can go attack the one near the edge.
Winning this stage gives you an Entei trophy.
