Event 4: Dino-wrangling
From SmashWiki, the Super Smash Bros. wiki
Dino-wrangling (いちおう恐竜だし, Well, I am a Dinosaur) is the 4th 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 giant CPU Yoshi on the Yoshi's Story stage with no time limit. The player starts with 3 stocks, while the giant Yoshi starts with 1 stock. Due to Yoshi's massive size (being even larger than a regular Yoshi under the effects of a Super Mushroom), he is very heavy and strong. However, his increased weight coupled with his low AI level means that he will often [self-destruct]] within seconds of the event's start.
