Similarly to Rare Slimes, Quicksilver Slimes cannot be stored in the vacpack, and cannot be kept in a Corral; instead their plorts are earned through the Nimble Valley activity. Their plorts also cannot be stored in the regular vacpack; they can only be stored in the Miles Tech Vacpack which is automatically equipped at Mochi's Manor. They also cannot be lost, as any produced by Quicksilver Slimes during the activity, discarded, or thrown into The Slime Sea is automatically transported back to the Miles Tech Vacpack. They also cannot be sold on the Plort Market, they instead can only be traded to Mochi Miles at her manor, earning 150 for every 10 Quicksilver Plorts.
Quicksilver slimes are lightning quick, and feed on electricity. This is generally accomplished by their moving really fast and slowly accumulating the static charge they generate. However, Mochi has decided to speed up the process and created a method for feeding them energy in a far more direct fashion.
Quicksilver slimes are not normally harmful to a rancher as the static they generate has a low current.
However, Mochi's method of feeding them a great deal of electricity at once makes quicksilver slimes overcharged with a current high enough to be harmful if touched. So be careful when firing those spark shots as a mob of well-fed quicksilvers could leave you zapped!
Mochi sells quicksilver plorts off-market and little is known about her buyers or their motives.
- Quicksilver plorts can be shot from the Range Exchange zone of Mochi's Manor into the Ranch zone, straight into into a Warp Depot or Refinery Link, essentially smuggling the plorts out of the area. Market Links however will reject the plort. Regardless of where the plorts are located when withdrawn, due to being unable to be stored in the regular vacpack they will always be collected back to the Miles Tech vacpack.
- Quicksilvers use audio used by the Fire Slime.
- 1.2.0 - Implemented.
- 1.1.2 - The Slime and the Plort are no longer vaccable, and now it was able to be fed with the upcoming Valley items; also still in the prototype stage. Shooting a Valley AOE and a Valley Small item would result in the slime dropping a plort, although the Valley Slow did not. It could be fed every two in-game hours.
- 1.1.0 - A prototype version of the Quicksilver Slime was added into the game's files. It used the Fire Slime model as a placeholder, and its plorts used the Tabby Plort model. It moved around faster than the other slimes, and it wasn't able to be fed anything.
- The Quicksilver Slimes may be based on Mercury, an extremely toxic silvery substance which is liquid at room temperature, and is capable of conducting electricity. Their name may also be a pun on both the slime's speed, and its silver appearance.
- Their speed and the antennae on their head may be references to the Marvel hero Quicksilver, who not only uses a similar pun, but has also been portrayed with two strands of hair pointed back in a similar fashion, and is also known for his speed.
- The slime's concept, particularly the fact that it feeds on electricity, may also be based on the Quicksilver from Spiral Knights; one of Nick's previous games.
- Prior to release, the roadmap for the Quicksilver Slime stated: Why doesn't the rest of the world know about Quicksilver Slimes? Why are they ONLY located in the Miles-owned Nimble Valley? I'm sure it's just a coincidence.
