Vine Slime

Vine Slimes, also known as Slugs, are slug creatures that crawl up and down vines in the depths of Torrential Maze in Yoshi's Story. They are blue and can move their two eyes from one side of their bodies to the other. These foes are indestructible and can only be avoided. They appear only in the aforementioned level.

Trivia

 * The official Shogakukan guide for Yoshi's Story does not mention Vine Slimes or their vines at all, and instead refers to the areas they are found in as containing Ghost Streams. This may suggest that Vine Slimes were added late into development, after the Shogakukan guide was first made.
