–Wolfgang

Rock Lobsters are neutral creatures found in Caves. They eat all minerals except for Marble, all of which can be given to them as food to befriend them. They grow over time, slowly regenerate their health, and come in a variety of rocky colors. They are also immune to the freezing effect of the Ice Staff.

When killed, they shatter and drop Meat, Rocks, and Flint. These mobs can be found in a Rocky Plains Biome.

Behavior

Rock Lobsters are slow-moving and live in herds. They repopulate and grow over time every 4 days; while they do so, their size, Health, and damage output increase, while speed decreases. They roam around looking for Rocks and Flint to eat, only fighting when they are attacked. When attacked, Rock Lobsters hide by mimicking large stones. While hiding, their stone shells absorb 95% of damage.

Like Pigs, Rock Lobsters can be convinced to follow and fight for the character when given any minerals such as Rocks, Flint, Gold Nuggets, or any Gems; however, they only follow for about 3 minutes (6 segments) per item (the "elemental" value of the item does not factor in to this). Each additional elemental item fed to the Rock Lobster will increase the loyalty time by another 6 segments, up to a maximum of 2.5 days (same as Pigs).

Rock Lobsters will go to sleep after spending 2 days awake. A sleeping Rock Lobster will awaken after half a day asleep. Time of day or darkness level does not factor into their sleeping habits. A Rock Lobster may also be put to sleep with the Pan Flute or with three Sleep Darts.

The Rock Lobster regenerates 10 HP per second, while in camouflage.

Hunting 

Rock Lobsters have high health and protect themselves from damage. They also live in herds and will defend each other when necessary. Additionally, their health slowly regenerates. All of this taken together means that Rock Lobsters are very difficult to kill. When possible, it's a good idea to separate one from the group before fighting it, or use ranged weapons since they are slow-moving, which allows for multiple hits in a short time.

Also an effective way to kill the Rock Lobster is to kite: hit it and run out of its range before it can hit back. It is also noted that while a Rock Lobster is sleeping, one can kill it with Gunpowder or Slurtle Slime, as once lit, those explosives will deal large amounts of damage to groups of sleeping Rock Lobsters, and they will not wake up and aggro the player. 9 Gunpowder can easily take out a fully grown Rock Lobster.

Below is the number of hits it takes with each weapon to kill Rock Lobsters and their offspring when playing with characters with a default damage modifier. The Weather Pain is not included due to the random nature of its projectile.

Weapon
No. of hits for	Immune	295-424	92-133	74-106	46-47	41-59	37-53	30-43	20-62	16-42	25-36	21-30	19-27	13-18	7-9	2

Rock Lobsters take 3 Sleep Darts to be put to sleep.

Don't Starve Together

In Don't Starve Together, Rock Lobsters cannot be brought to the surface.

Tips

• Rock Lobsters can take out giants with little to no effort. Having high health and damage, regenerative abilities, and immunity to fire and ice, they are a good solution to any boss in the game, especially the Ancient Guardian.
• A group of Rock Lobsters can easily take out a herd of mating Beefalo if left unsupervised. However, one or two Rock Lobsters will easily be stopped by a large herd, as they will be hit too often to come out of hiding.
• Another above-ground use for these creatures is against hound attacks. By using this guide, the player can easily defend against hounds. If hiding fails, simply run around the pen and let the hounds aggro onto the lobsters.
• After the April 27, 2015 Update not only was their overpopulation problem fixed, but also now if brought on overworld, as soon as they stop following the player, they'll wander towards the closest Rocky Biome and will stay in its borders (like how beefalo tend to search for Savanna). This can be used to create a contained environment for them to use against hounds and bosses.
• A Dragonfly will kill Rock Lobsters within a few hits, and her AoE attack is particularly devastating. While this makes Rock Lobsters unreliable in a fight against the giant, a player can use a Dragonfly to quickly reduce their Rock Lobster numbers in the event of overpopulation.

Trivia

• Rock Lobsters were added to the game in the It's Not a Rock! update.
• Rock Lobsters may have been inspired by the B-52's song "Rock Lobster", although this version doesn't appear to play or listen to rock music. Further proof is that Rock Lobsters were added in the "It's Not a Rock" update, which is similar to the song's lyrics.
• Rock Lobsters may also have been inspired by the actual rock lobster, although this version is a lobster with a shell made out of rock. Rock Lobsters have one large claw and one small one, a trait similar to that of fiddler crabs.
• It takes 40 days for a Rock Lobster to reach its maximum size, health, and attack power.
• Rock Lobsters drop meat, indicating that the rock is merely a shell thus they are most likely organic creatures and not a living rock or silicon-based life-form.
• Prior to the April 27, 2015 Bugfix, Rock Lobsters on the Surface would breed uncontrollably and eventually fill the entire world.
• The Rock Lobsters' behavior on the Surface World might have been be an intentional representation of an invasive species, but now that the Rock Lobster overpopulation bug has been fixed, the invasive species intention theory faces increased ambiguity.
• One of Maxwell's quotes upon examining them, "I banished these guys down here for a reason." may be because of the rapid breeding they do above ground.

Bugs

• If the character befriends a Rock Lobster and several Spiders start to attack the character, the Rock Lobster will only attack the first Spider and not all of them.
• If a character enters or leaves a cave with Rock Lobsters as followers, the Rock Lobsters may die.
• If the player attacks a hidden Rock Lobster with a ranged weapon, it will come out of hiding and then be passive to any following melee attacks for a while without hiding.
