Sky Frogs

A void-skyblock NeoForge 1.21.1 modpack built around Productive Frogs.

Status: v1.0 (released). All six tiers (Cave / Geode / Bog / Tide / Infernal / Void) are built and playable end-to-end - frogs for ores, gems, organics, the ocean, the Nether, and the End - finishing with a real dragon expedition and a singularity-powered endgame that caps off in the Sky Frogs Master Frog trophy. Ongoing post-1.0 work is polish: balance tuning, final trophy art, and the branding gallery. Feedback welcome on the community Discord or via GitHub Issues.

You spawn on a speck of land over the void. No ore to mine, no Nether to raid, no mountain to dig into. What you've got is frogs - and out here, that turns out to be the same thing as a mine.

Everything from your first iron to the endgame comes through Resource Frogs: six species of breedable frog, each one eating its matching slimes and handing back Froglights you smelt into the real thing. Sky Frogs wraps that core mod in an FTB Quests campaign that walks you from a single dark-room slime farm to a frog for every resource in the game.

Features

• Species-gated progression. Six frog species, unlocked in order - Cave, Geode, Bog, Tide, Infernal, Void - each one a whole new family of resources. Finish one species' chapter to bootstrap the next.
• You already know the controls. Every interaction is a vanilla right-click: glass bottles, slimeballs, water buckets, frog eggs. No custom UIs to learn.
• No mining shortcuts. Laser drills, quarries, digital miners - recipe-stripped or hidden. The frogs are the path, and the pack enforces it. (Builders get one curated exception: a string-mesh sieve over dirt and moss that drops saplings and garden flora - decor only, never resources.)
• Cross-mod by JSON. Any modded resource can be made frog-farmable with a single slime_variant JSON file, so the whole modded-resource ecosystem plugs into the same loop. No Java, no source-fork.
• A questbook that actually guides you. FTB Quests walks every tier: a chapter per species, plus side chapters for the tech mods. If you're lost, the answer's in the book.
• An illustrated field guide, too. Productive Frogs' in-game Patchouli guide is in your inventory from the first login (and craftable if you lose it), with a Sky Frogs section covering the void-skyblock specifics - a reference shelf alongside the step-by-step quests.
• A completionist victory lap. Two census chapters count every froglight in the pack - the full vanilla roster laid out as an actual tree frog, the modded set column by column - and every name on the list is genuinely craftable. No lottery tickets, no dead checkboxes.
• Built from player feedback. Most updates start as somebody's Discord message or CurseForge comment - the welcome chapter hands you the invite (or click Join the Pond in-game).

How to Play (your first hour)

1. Spawn on your island with a starter kit: saplings, a water bucket, a lava bucket. The questbook opens itself.
2. Make cobblestone the old-fashioned way: water next to lava, infinite cobble. (Enjoy the pickaxe while it lasts.)
3. Get a second water source. An Ex Deorum barrel catches rain; bottle it onto your island for an infinite water square.
4. Wall off a dark room - at least 5x5 and 3 tall. Cave Slimes spawn in the dark here; they're your first ore source, and bigger rooms fill faster.
5. Farm them for slimeballs, and keep an eye out for the occasional Iron Slime.
6. Finish the Welcome chapter and you're handed a Bottle of Cave Frog Eggs (a breeding pair's worth).
7. Pour it on water. Cave Frogs hatch. Feed one an Iron Slime, an Iron Froglight drops, smelt it: your first iron.

By the end of a session, iron is a frog's problem, not yours. The book drives the rest.

The Six Frog Species

Each tier extends with modded resources as those mods ship in the pack. The endgame: compress a thousand of each of the frogs' resources into its own Singularity (a proof you automated every farm - one per vanilla resource), fold the full set into the Ultimate Singularity, and craft the Sky Frogs Master Frog, a trophy that says you out-frogged the game.

Mod Highlights

The full mod list is in the repo at docs/mod_list.md. The load-bearing picks:

• Productive Frogs - the core mod. Six frog species, hand-operated appliances, datapack-driven slime variants.
• Skyblock Builder - void worldgen, the starter island, per-player island UI.
• Ex Deorum - crucibles, the porcelain bucket, rain-collection barrels (your second water source), and the End Cake (your ticket to the dragon). Resource sieving is disabled in this pack - Tier 0 runs on a dark-room slime farm - but a small builders' sieve lane drops decor flora and starter food seeds.
• FTB Quests + Library + Teams + Chunks + Ranks + Essentials - questbook, claims, party support, server admin, /home / /spawn.
• JEI + Jade - recipe browser and in-world block info. Standard quality-of-life.
• Sodium + Lithium + FerriteCore + ModernFix - the standard performance stack.
• Mekanism (Tier 2 verb) - power, Metallurgic Infuser, Enrichment Chamber.
• Powah! + Flux Networks (the power-scaling arc) - Furnator to Reactor, wireless energy everywhere - and every Powah material plus Flux Dust is frog-farmable. On a void skyblock, the frog is the uranium mine.
• Just Dire Things + Building Gadgets 2 (Tier 3 verb) - utility / automation toys; the JDT goo and gadget chain.
• Industrial Foregoing + IF Souls (Tier 4 gateway) - the Dissolution Chamber is the pack's slime engine; resource-threaded chamber recipes for every tier. Souls adds an optional Tier 6 flex: summon and farm the Warden, entirely from frog-farmed sculk.
• Iron Jetpacks (Tier 4 verb) - FE-charged flight; what makes the void-Nether fortress run feasible.
• Refined Storage (Tier 5 verb) - the digital storage + autocrafting network, gated on nether quartz.
• Extended Crafting (Tier 6 verb + endgame) - the tiered crafting tables and the Quantum Compressor that turns froglights into singularities, ending in the Master Frog trophy.
• Quality of life, the modern set - GraveStone (your items wait for you), Inventory Essentials (bulk ctrl-shift-click moves), Cable Facades (hide pipes in any block), Extreme Sound Muffler (silence the plap plaps, per sound), Botany Pots + Botany Trees (toolless self-tending planters - trees included).

FAQ

Why frogs? Because "feed a slime to a frog, get an ingot" is a loop you can explain in one sentence and never tire of. It rides on vanilla idioms (frogspawn, water bottles, slimeballs) so there's almost nothing new to learn, and the six species give the campaign a clean tier-by-tier shape that keeps growing.

Can I add my own modded resource as a frog target? Yes; that's the whole design. Drop a single JSON at data/<namespace>/productivefrogs/slime_variant/<name>.json, wrap it in neoforge:conditions for mod_loaded, and the matching-species frog will eat it. No Java, no PR to the underlying mod.

Is automation possible? Yes, but never required. Productive Frogs is hand-operated by design; the pack is completable with hoppers, water streams, and patience. Tech mods make it faster, not mandatory.

Server-friendly? Yes. Each release ships a server pack alongside the client. Party support via FTB Teams, claims via FTB Chunks, /home and /tpa via FTB Essentials. Balance is single-player-tuned for now; multiplayer tuning is a later stretch goal.

Will my world break on updates? Not on a normal update. Now that the pack is 1.0, world-breaking changes bump the major version and get flagged in bold at the top of the release notes; hotfixes and content additions never break worlds.

Modrinth release? Not planned. The FTB utility stack and Productive Frogs are CurseForge-only, and Modrinth forbids inlining CF mods as overrides. FTB Quests is load-bearing for the campaign, so CF stays the sole channel.
