Each of the 12 characters have their own rarity curve. The individual character PFPs are ranked on the relevant character's rarity curve based on its unique combination of attributes. Where the PFP falls on the rarity curve determines its Slime Score.
Slime Score attributes:
Zim is relying on you to help him take over the world! Just a week after the drop, minions can participate in the next phase of Zim’s ultimate plan. In the first set of challenges, you’ll be able to swap your characters for Slime. Your character’s Slime Score determines how much Slime they’re worth.
Each character will have a designated Slime Score of one, two, three, four, five, or 10. They can then be exchanged for an amount of Slime equal to their Slime Score. Minions who collect 10 Slime can unleash a powerful monster Mashup. But act quickly! Only 5,000 Slime will be available to be redeemed and Slime from last season cannot be used in this season.
Get ready for the big Slime, beginning November 17th.
Finally, for what is perhaps the most important part of Zim’s ultimate plan to “help” humanity, once a minion collects 10 Slime they can unleash an ultra-rare and powerful Mashup.
These mashups are so hideous, so vile, so perfectly evil that only 500 of them can ever exist. Together, they’re powerful enough to topple Earth’s mightiest warriors! Will you get Zim mixed with Krumm? Perhaps Daz and the Gromble? So many possible combinations. SO. MUCH. CHAOS!!!
It’s almost time to embrace the chaos. Mashups start November 21st.
