The Slugs are mini-bosses that appear in Yoshi's Story. To defeat it, Yoshi and his species must hit it with fireworks 3 times (Eggs are useless, as they will just bounce off the slug, the fireworks must make contact with the slug to damage it). They appear mostly in the Cavern.
Trivia[]
- There is also another slug boss named Sluggy the Unshaven in Super Mario World 2: Yoshi's Island.
