Productive Frogs

v1.4.0 - 2026-05-26 - the Spawnery (skyblock bootstrap)

A new V1 appliance for skyblock and other restricted-biome packs, plus a round of appliance/JEI fixes. The Spawnery turns glass bottles into bottled frogspawn so the frog side of the loop can start where swamps and mangroves are unreachable - off by default, and fully pack-tunable.

Added

• Spawnery - a skyblock-bootstrap appliance, disabled by default (spawnery.enabled). A furnace-style block that turns glass bottles into bottled frogspawn, fueled by slime balls (one ball per bottle). A primer is required: a slime ball primes plain vanilla frogspawn, or a species primer (iron ingot for Cave, amethyst shard for Geode, bone for Bog, prismarine shard for Tide, blaze powder for Infernal, an ender pearl for Void) primes that species' eggs. Species defaults are normal-world resources; modpacks retune them per species via the spawnery_primer/<species> tags. Hopper-aware. Crafted from 5 cobblestone + 3 planks + 1 bonemeal. When disabled it is uncraftable and hidden from JEI + the creative tab. The primer set is pack-overridable via the spawnery_primer/<species> item tags. See docs/spawnery.md.

Fixed

• The Slime Milker now has a crafting recipe (5 cobblestone + 3 planks + 1 slime ball). It previously shipped with a loot table but no recipe, so a survival player had no intended way to obtain it (only creative / /give).
• Slime Milk variants now show individually in JEI. Every variant appeared in the creative tab, but JEI collapsed them into a single Slime Milk Bucket (a missing subtype interpreter); each variant is now its own JEI entry with its info page.
• Item tooltips now render in the Slime Milker and Spawnery GUIs. Hovering a slot in either appliance showed no tooltip (NeoForge 1.21.1's container screen doesn't render tooltips unless the screen asks it to); both now do.
