Pebble Spider

The Pebble Spider (a.k.a. the Kneecap Paste Spider), is a formidable enemy with jumping abilities that appears in large groups. They secrete a paste-like silk from their mouth which they use to glue natural objects, like wood or stone, to their backs as armor. It also has the capability to secrete an acid that can burn through said natural objects. They have a chance to drop silk or a smoothstone.

Trivia

 * It is possible for Pebble Spiders to be stuck out of bounds.
