Tentacle Spots are a rare item with a 20% drop chance from a killed Tentacle and a 40% chance from a killed Big Tentacle. They can be used to craft the Feather Hat, 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.
The Reign of Giants DLC adds another use for Tentacle Spots as one of the ingredients for a Rain Coat. Befriended Catcoons can also produce Tentacle Spots.
In the Shipwrecked DLC, Tentacle Spots can be obtained by killing the tentacles spawned by the Quacken.
- Multiple characters suggest that Tentacle Spots are the genitalia of the Tentacles, supported by Maxwell's quote, "This is how they reproduce".
