Whether you’re interested in statistics or want to know if you’re entitled to bragging rights, stick around and let’s get into it.
## Slime RNG Rarest Slimes
This Rarest index is up to date as of *May 7th, 2026*.
### The Rarest Of Them All
The true rarest Slime to roll in Slime RNG is the **Inverted Shiny Huge Frosty**, coming in at a **1 in 668.75 Qn** (Quintillion).
But let’s take a step back and explain how the Slime Index works.
Slimes have different variants, which you can roll, including **Base**, **Big**, **Huge**, **Shiny**, and **Inverted**. All Slimes included in the base index have alts of themselves for the other variants. This means it’s pretty easy to know which Slime is the rarest based on which Slime is the rarest in the base index.
Some of the variants can overlap, which is how we determine the true rarest. The only two categories that don’t appear together are Big and Huge, because they both influence size.

It seems you’ve stumbled upon my bio! I’m Sho, your local weeb. Off the clock I am typically watching anime, reading manga, or doing art. I think it’s safe to say that all my unpaid thoughts revolve around anime… That said, watch One Piece! (Or don’t, I’m just a biography.)
