The Tarr, referred to by the Overscan readout as a Tarr Slime, are Largo Slimes that have eaten a plort that it does not produce, transforming it into a hostile abomination that consumes other slimes and replicates on doing so. Due to this, they can potentially spawn anywhere at any time of day, and is one of the main threats to a ranch.
They are weak to water, and during the day a single splash is enough to dispatch them. At night they gain more health and require two splashes; the first will remove its rainbow coloring along with its ability to replicate, and the second splash will dispatch them.
Largos cannot eat plorts in Casual Mode, so they do not appear.
The tarr are formed when a largo eats a plort unlike the ones it produces. A terrible transformation occurs that turns the slime into a sludge filled with a swirling, prismatic array of colors and a relentless appetite. The tarr seek only to consume and replicate. Because of this, it can spread rapidly throughout the ranch.
The only way to stop a tarr outside of incinerating it or throwing it into the slime sea is with fresh water. One splash will stop a Tarr from spawning new Tarr, and repeated splashes will destroy it entirely.
Alternatively many ranchers recommend running away with their arms waving, and screaming.
The tarr are the single biggest threat to ranchers. The tarr will seek out slimes to consume and replicate themselves, but will also devour chickens, rot crops in their proximity, and even devour ranchers!
Remember: ranching largos may be highly profitable, but one stray plort and you could wind up with a devastating tarr outbreak.
The Tarr produce no plorts, only more tarr. And then more tarr still.
Tarr are formed after a largo eats a plort it does not produce. They are hostile towards the player, chickens, and other slimes, and they can perform huge jumps which aids in getting to their intended target. Tarr can inflict Fear on other slimes, and can grab slimes from a distance with a tentacle-like appendage which limits the slime's movement. When one consumes a slime it will produce a clone of itself in the process. They can consume hens and roostros, but will not produce clones. Any Fruit, Veg and Spicy Tofu that come into contact with Tarr will instantly decay.
Tarr are vulnerable to Water and Ancient Water; coming into contact with water will make them lose their rainbow colouring which stops them producing more Tarr when they consume slimes. During the day a single splash of normal water from the vacpack is enough to dispatch a Tarr immediately. At night, Tarr require two shots instead of one. Being immersed in bodies of water, making contact with Water Springs, Oasis moisture barriers, and Fountains will deal half the damage of water shot from the vacpack. Ancient Water will immediately dispatch Tarr regardless of the time of day. Tarr despawn on their own after approximately 1 in-game hour, or 1 real-time minute.
They can be placed onto a Slime Stage which halts their behaviors, but their despawn timer will not be halted and can despawn while on it. They cannot be applied with Fashion Pods, and do not respond to Slime Toys.
Main article: The Slimeulation
A digital equivalent to Tarr - sometimes referred to as Digitarr - appear as the sole threat within the virtual space of Viktor's Slimeulation, and appear out of corrupted rifts which spawn after 4 in-game hours.
Digitarr behave almost exactly like their standard counterparts, including sharing their weakness to Water. Digitarr are additionally weak to Debug Spray, and will force three-to-four Glitch Slimes out of the Vacpack inventory when successfully dealing damage to Beatrix. If Digitarr are left to their own devices and despawn on their own, they have a chance to produce two more fresh Digitarr in its place; this does not occur if dispatched with Water or Debug Spray.
Note that on a Casual Game, Digitarr do not appear; their rifts however still do.
- Because of their weakness to water, it is recommended to get the Water Tank upgrade for the Vacpack first and keep it filled with water at all times.
- If the player doesn't have water they can vacuum the Tarr to shoot it into the The Slime Sea instead or into an Incinerator. If the ocean is too far away, simply shoot them as far away as possible.
- If the player is in the Glass Desert, they can vacuum the Tarr to shoot it into an activated Fountain.
- If the player is close to a pond, they can shoot the Tarr into the water.
- Ancient Water will kill Tarr instantly, which is very good during night time when you need to shoot water twice to dispatch them and there's a lot of Tarr.
- The Pulse Wave Upgrade can also be another way of avoiding Tarr since it can keep them away if they get too close.
- The Tarr are marginally less threatening than Feral Slimes, since they target other Slimes as well as the player and can be dispatched with water. If there are too many Feral Slimes in a Danger Zone, it may be worth converting one to a Tarr, have a Tarr outbreak, then shooting the Tarr with water.
- Areas with a diverse range of slimes are more prone to Tarr outbreaks; the last area of The Dry Reef for example often gets filled with Tarr because of the four types of slimes that spawn there.
- In The Glass Desert, the protective barrier produced by restored Oases damages and quickly kills Tarr when they enter the barrier or form within it, making them safe spots from Tarr outbreaks.
- 1.4.0 - Implemented the digital variant of the tarr along with The Slimeulation.
- (Undocumented) Tarr now have 100% chance to reproduce when consuming slimes, if they are able to.
- 1.3.2 - Fixed a bug that caused tarrs to stop chomping if you stood still. The best ways to deal with tarr is to blast them with water or to RUN!
- 1.1.1 - The Tarr's Slimepedia entry is now immediately unlocked in Casual Mode… but don’t worry, that’s as far as they go in Casual Mode.
- Fixed bug where on certain graphics settings, a biting Tarr appeared to have an additional smaller Tarr inside it. Creepy.
- Fixed bug where Tarr and Fire Slimes were bounced too aggressively out of ponds.
- 1.1.0 - Fixed bug where Tarr was occasionally playing some incorrect non-Tarr slime sounds. Though adorable, it had to change.
- 0.5.1 - Fixed bug where Tarrs placed on Slime Stage could quickly escape. Maybe it wasn't a bug though and deep down, tarrs are just really shy, though this is very unlikely.
- 0.3.5 - Water is now more effective against Tarr, though just as before, they are twice as hard to kill at night. Tarr also now visibly flash red when hit. At first, we thought it was because the water made them blush but then they exploded...
- 0.3.5b - Fixed bug causing feral slimes and tarr to possibly cause continual damage to the player
- 0.3.3 - The Pulse Wave has received an overhaul: the visuals have been greatly improved and the knockback and its effectiveness have been increased against largos and tarr.
- 0.3.0 - New visual effect for Tarr death explosion. It’s prismatic and full of joy because, in death, one must celebrate the tarr's life.
- 0.2.5 - Fixed bug where the Tarr music would sometimes continue after teleporting away from the Tarr.
- 0.2.4 - Fixed bug where Boom Rock Largos would eat fruit to transform into Tarr.
- 0.2.3 - Make Tarrs in freshwater react as if hit by water.
- Before 0.2.0 - A prototype of The Tarr was dark red and was a generic Largo Slime. It was later changed to the current model.
The Tarr's presence and negative impact towards the game's ecosystem by decaying food on contact and being hostile towards - and consuming - living beings may be loosely based on marine oil spills, a form of pollution which has a negative effect on wildlife and the environment whenever one occurs. Their rainbow coloring is reminiscent of the pattern that forms when oil comes in contact with water. Their formation when a Largo consumes a plort may be based on the process of organic matter decaying into oil, and tarr replication through consumption of slimes may be the result of reproductive cloning, or asexual reproduction. Their name is a reference to tar, and their tagline in the Slimepedia, "Those awful, ravenous, rainbows", is an acronym for "Tarr". It notably has a similar texture to Primordy Oil, an item with a similar inspiration.
Digitarr's appearence and self-replicating behavior - specifically consuming the slimes within the slimeulation to produce more tarr and having a chance to spawn two tarr when it despawns naturally - shares similarities with a computer virus. The name "digitarr" is the name given for the tarr icons accompanying the tutorial about them within the Slimeulation, and is a portmanteau of the words "digital" and "tarr".
- There are two achievements associated with Tarr; Once Bitten, Twice...Bitten and Best of the Worst. Once Bitten, Twice...Bitten can be obtained by holding the tarr for 15 seconds. Best of the Worst can be obtained by putting(?) the tarr on the Slime Stage.
- Tarr cannot be equipped with Fashion Pods.
- Tarr has a similar texture to Primordy Oil.
- They do not consume Gold Slimes, Twinkle Slimes or Gordo Slimes, but can consume Lucky Slimes.
- Despite having a diet of water, Tarr can eat Puddle Slimes without being harmed themselves. The water itself however can harm Tarr.
- Standard Tarr are susceptible to Debug Spray; however this is not normally possible during standard gameplay.
