Tentacle Spots

"These are better off unmentioned."

- Wendy

Tentacle Spots are have a 50% chance to drop when a Tentacle or Big Tentacle is killed. They can be used to craft the Feather Hat and the Rain Coat, and Wickerbottom can use them to craft the Book "On Tentacles". Tentacle Spots do not spoil and can also be burned as fuel in a Campfire or Fire Pit.

Trivia

 * Multiple characters suggest that Tentacle Spots are the genitalia of the Tentacles, supported by Maxwell's quote, "This is how they reproduce."
