Hatchling

Horror parasite lifecycle mod for Minecraft 1.21.1 (Fabric).

Eggs hatch into larvae that hunt cows, incubate on their backs, then burst the host into a hostile alien — which lays and throws more eggs until population and generation caps stop the spread.

EGG (block / thrown) → LARVA → latch on COW → incubate → BURST → ALIEN
