Sky Frogs is a NeoForge 1.21.1 void-skyblock modpack built around Productive Frogs. You spawn on a tiny island over the void; every ingot from early iron to endgame comes from Resource Frogs instead of mining.
Progress through six frog tiers (Cave, Geode, Bog, Tide, Infernal, Void) for ores, gems, organics, ocean loot, Nether and End resources. FTB Quests and an in‑game Patchouli field guide walk you from a slime-powered start to singularities and the Sky Frogs Master Frog trophy, with strict no-mining shortcuts and JSON-driven modded resource support.
