EvoCraft Update — Penguins, Nether Mining, and Fixes
🐧 New Creature: The Penguin
A fully custom seabird has waddled into the mod — built from scratch with its own model, animations, and behavior. Penguins live in colonies, dive for fish, slide on their bellies, and fully participate in the evolution and mutation systems.

How to tame one:
Penguins aren't tamed with a fixed ritual — it's a gamble. Feed a wild penguin raw fish (Cod, Salmon, or Tropical Fish) and there's a chance it accepts you as its owner. Cod works best. Each fish that doesn't land the tame still builds trust, so your odds climb the more you feed it — up to a cap. Missing a few times isn't bad luck ruining your day; it's the system working as intended.

What they do:

Swim and dive — penguins are amphibious. They'll seek out water on their own to fish, diving down to hunt and surfacing with a catch.
Fish for you — a tamed or wild penguin will periodically dive and bring up raw fish, sometimes rarer finds (nautilus shells, prismarine, even a Heart of the Sea) if it's carrying the right traits.
Slide on ice — walk onto any ice variant and a penguin will belly-slide across it, picking up speed.
Form colonies — get 5 or more penguins together and they become a colony, boosting both breeding and fishing rates for every penguin nearby. This stacks the more you cram in, up to a cap — a proper penguin farm is genuinely worth building.
Breed and lay eggs — feed a pair fish while both are in love mode. They lay eggs that carry their genetics forward, just like every other creature in the mod — hatch them in an Incubator to raise the next generation.
Command a dive — sneak + right-click a tamed penguin near water to send it fishing on demand.
Mutations: Penguins have their own line of 8 mutations — Cryogenic Feathers, Ice Walker (freezes water underfoot as it walks), Conductive Feathers, Thermal Adaptation, Prismatic Feathers, Void Feathers, and the mythic-tier Aurora Feathers, plus a non-exclusive Deep Forager trait. Each has its own look and its own egg variant, so a mutated penguin breeds true.

Find them naturally in snowy beaches, frozen oceans, ice spikes, snowy plains/taiga, and frozen rivers.

⛏️ Mutagen Overhaul: From Nether Mining, Not Just Grinding
Mutagen — the currency behind Mutation Lab work — now has a real supply line instead of being a lucky drop from killing mutated animals.

New ore: Mutagenic Crystal Ore, found throughout the Nether. Glows faintly so it's spottable in a dark cavern.
Mine it (fortune-affected, silk touch works too) for Mutagenic Crystal.
Smelt or blast the crystal into Mutagen — same as any ordinary ore.
Mutated-mob kills still occasionally drop a bit of Mutagen as a bonus, but it's no longer the main way to get it. Go dig.
