Largo Slimes are the result of a pure slime eating a plort not of its type. They are far bigger than pure slimes and can no longer be stored in the vacpack in this state; instead only being able to fit onto the nozzle. A Largo cannot revert back to a pure Slime.

A Largo Slime adopts the favored food, traits, and abilities of the Slime it was before transforming and the Slime type of the Plort that it ate as a pure Slime. When fed, they produce two Plorts; one for each of its base Slime types. This is doubled to four - two each - when eating one of its favored foods, making them far more efficient for ranching.

There is a risk to ranching Largos however; if a Largo eats another Plort of a type that it does not produce, it transforms into a Tarr; a hostile Slime that devours other Slimes and produces more Tarr when it does so. This is often referred to as a "Tarr outbreak".

It is not possible to create Puddle, Fire, Quicksilver, Lucky, Gold, Twinkle or Glitch Largos.

Slimepedia Entry

Largo Slimes are a hybrid of two slimes resulting from a slime eating a plort unlike its own. They are twice as big normal slimes and have a combined diet of their two source slimes, making them enticing for ranchers that want to maximize their profits.

However, a largo is too big to vac and can only be transported using the end of the vac nozzle. This makes them difficult to control if things get out of hand.

Rancher Risks:
In addition to largos being more difficult to manage and having the combined powers of two slimes, an even greater threat to ranchers lies within these super-sized slimes. If a largo eats a plort unlike its two source slimes, it will transform into a ravenous tarr slime!

Ranchers need to be very careful when dealing with largos or risk an outbreak of tarr that can quickly overtake their entire ranch. Always carry a full tank of water just in case!

When a largo eats, it produces plorts of both source slime types, making them potentially very lucrative for ranchers that can deal with the added risk of keeping them.

Largo Chart

This chart shows all the Largos that are currently available in the game.
Note: The saber slime only exists in largo form.
An in-game largo chart.


  • Largos are too big to be sucked into the vacpack. Instead, they get stuck to the nozzle, then they can be transported to another location and either shot or released there.
    • They cannot be transported by any warp tech and must be either created, or brought by foot to any location.
  • When fed the favorite food of its source slimes, it can make four plorts (two from each source slime) at once!
  • You can obtain the Achievement: Fireworks if you grab a Boom Largo and launch it into the air just before it explodes.
  • Hunter Largos are very dangerous since they become instantly feral after being created. Because of that, you need to have something to feed and calm them down.
    • Also, if they get too Agitated, they will become feral again, so keep them calm or place a taming bell next to their corral (a music box helps).
  • Note: It's not possible to produce a Gold Largo as none of the other slimes eat Gold Plorts. It's also impossible to get Puddle Largos because slimes ignore Puddle Plorts and Puddle Slimes ignore other Plorts. The same goes for their Fire Slime counterparts. A Lucky Largo is also impossible since Lucky Slimes do not produce Plorts. Inversely, it is not possible to acquire pure Saber Slimes, even through snaring a Gordo, as pure Saber Slimes do not spawn, and the Saber Slime has no favorite food. Quicksilver slimes also cannot be largoable as they cannot be vacced up and you cannot bring quicksilver plorts outside the range of the portals leading to nimble valley.
  • The Achievement "Diversification" is earned when you have 10 Largo types on your ranch.
  • Quantum Largos can be difficult to manage as they create ghosts and use them to get out of the corral. Feed them regularly and they won't get out of the corral.

Spreading Behavior

When there are many of one type of slime and just one of another type of slime, it is possible to mix them using only the food that the latter slime type eats (e.g. Veggies for a Rock Slime among several Dervish Slimes). Refer to the table for more info:

A single Rock Slime and several Dervish Slimes. SlimeRancher-2017-09-01-03-30-35-14.png When the rock slime is fed a veggie, the plort it produces is eaten by a Dervish Slime. The Rock Dervish Largo eats a veggie to produce another rock plort and a dervish plort.
Several Rock Dervish Largos. SlimeRancher-2017-09-01-03-36-29-90.png The Rock slime in the image on the left next to this image was fed veggies, and Dervish Slimes ate the Rock plorts, becoming Rock Dervish Largos and eating more veggies, etc.

Feral Slimes are Largos that are particularly grumpy and will try to take a bite out of Beatrix if she gets too close. But maybe if they're given a bite to eat...

  • The word "Largo" is Portuguese for the word large. According to Nick the term largo is a nod to Spiral Knights, possibly referencing the Toxilargo in particular.
    • The Italian word for "large" is the same as the Portuguese one.
    • It is also the Spanish word for long.
  • Their Slimepedia Icon shows a Phosphor Tabby Largo with its source slimes.
  • Naming conventions for Largos follow a set order in which the combined slimes' names are placed, which is as follows: Pink > Saber > Quantum > Honey > Phosphor > Mosaic > Tangle > Boom > Rad > Rock > Tabby > Hunter > Crystal > Dervish.
    • For example, Pink Quantum, Honey Crystal, Saber Tangle, and Rad Tabby are all officially correct names for Largos, while Honey Pink, Rock Saber, Crystal Rock, and Rad Quantum are not.
    • It should be noted, however, that Boom Phosphors do not follow this convention.
  • When a Quantum Hunter Largo creates a ghost, it has the eyes of the Hunter Slime while the original largo has the eyes of a Quantum Slime.
    • This was actually, in fact, a bug that was later fixed in the Better Homes Update (0.5.1).
  • Different Slimes seem to react to becoming a largo differently, such as Pink Slimes always staying pink as largos, or that Tabby Slimes almost never turning gray as largos (only 5/13 are grey), just looking like the other slime, but bigger, and with ears/tails and a "cat face". Saber Slimes only add saber fangs and Hunter Slimes only keeping their 'bandana', tails, their wild nature, and that only 3/13 are brown.
  • Pure Slimes will awe at the sight of certain Largos.
