The Tarr

"Those awful, ravenous, rainbows."

Diet:
Rotten Veggies, Rotten Fruit, Meat, and Slimes, but not Gold Slimes or Gordo Slimes.

Favorite:
Ranchers! Or anything really.

Slimeology:
The Tarr are formed when a largo eats a plort unlike the ones it produces (ex. a pink tabby largo eats a honey plort). 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 through out 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. However, fresh water does not kill the Tarr and it will continue to expand. Tarrs do go away naturally after a while of being inactive (in a place with nothing to destroy).

Alternatively many ranchers recommend running away with their arms waving, screaming.

Rancher Risks:
The Tarr are the single biggest threat to ranchers. The Tarr will seek out slimes to consume and replicate themselves, but also devour chickens, rot crops in their proximity, and even devour ranchers!

Plortonomics:
The Tarr produce no plorts, only more Tarr. And then more Tarr still.

Tips

 * Ranching largos may be highly profitable, but one stray plort and you could wind up with a devastating Tarr outbreak.
 * However, easiest way to do it is to put them in the Grotto, since even if you get a Tarr outbreak, they can't get in and out of it. They're trapped.
 * The Tarr produce no plort to sell. You can enclose them in a corral but they will die shortly after.
 * Certain areas are more prone to Tarrs than others. The last area of the Dry Reef, for example, often gets filled with Tarrs because all 3 diurnal slimes that live in the Dry Reef (Pink slimes, Rock slimes, and Tabby slimes) spawn there. The Moss Blanket has more slime types, so Tarrs also have a high chance of happening there, but luckily it has many areas of water, so it's easy to get rid of them.
 * If you don't have water when encountering a tarr, you can use your vacpack to toss it into the ocean.
 * If you manage to hold onto a Tarr for 15 seconds, you get the Achievement: Once Bitten, Twice...Bitten.
 * You can tell if The Tarr is nearby by a change in music
 * Puddle plorts will also kill Tarr, and unlike water they can be stored in a silo. Some ranchers have used this to turn The Grotto into a Tarr shooting range. Video
