Spider Eggs

"A tiny package full of death and destruction."

- Wendy

Spider Eggs are acquired by destroying a tier 3 Spider Den or killing a Spider Queen. They can be planted on the ground by picking them up from the inventory and clicking the ground with the right mouse button. This creates a tier 1 Spider Den, which then grows like normal. The Spider Eggs can be used to relocate Spider Dens to any specific place, often an area where they can safely contain the Spiders for Silk farming. Eggs can also be great fuel for Campfires, adding a lot of burn time. Webber can craft Spider Eggs using 12 Silk, 6 Spider Glands, and 6 Papyrus and also starts the game with one in his inventory.

It is possible to get multiple Spider Eggs from a single Spider Den, allowing players to actively increase the number of nests in a single map. This can be done by waiting for a den to turn into a Spider Queen, which will leave behind a level 1 den. Then kill the queen to get her Spider Eggs.

Trivia

 * When removing/inserting Spider Eggs into one's inventory, the item makes a squelching noise.
 * Despite what Wilson says after inspecting Spider Eggs, they will never hatch unless the player manually plants them.
