Puffy

Puffy is a crafted ethereal tied to Candyland, and at 1 in 195 million the rarity is staggering for a slime that only reaches Tier A. It is strong, but the crafting requirement and the sub-S ranking mean you pursue Puffy as a build project rather than a pure power upgrade you would otherwise prioritize on raw stats.

Keep it if you are completing the crafted-slime set or routing through Candyland anyway, since otherwise the Tier S ethereal alternatives deliver more combat for a comparable investment of time. The honest comparison is Derpy at half the rarity and a higher tier — Derpy simply out-fights Puffy, and players choosing between them on combat alone should not equip Puffy first.

After Crafty and SlimeSlimeSlime, Puffy is the third crafted slime players meaningfully chase. By the time you reach this build, the recipe pattern is muscle memory: Cavern, Redwood Forest, Candyland. Until Astro and Sunny in the rarer crafted bands finally land, Puffy represents the deepest realistic crafted pull for most accounts, and that lineage is the real reason to chase it.
