Tentacle

Tentacles appear from the swamp and hit for very high damage. They are aggressive, attacking you or any other animal closeby.

They drop Tentacle Spikes when killed, which are more effective than spears. They will also drop Tentacle Spots, which are used to make the Feather Hat.

NOTE: Do not be wandering around in the swamps, off of the path. Walking on the swamp will aggro the swamp monster. You can outrun it, but any pigs following you will become distracted, trying to kill it.
