Frogs are one of Minecraft’s most charming passive mobs, and they are also the only way to obtain froglights, the brightest light-emitting blocks in the game. The catch is that frogs are surprisingly fiddly: their colour, the froglight they produce, and the whole breeding chain all hinge on a few specific mechanics. This guide walks through every verified step, from temperature variants to farming all three froglight colours.
The three frog variants
Frogs come in three variants: temperate, warm, and cold. They differ only in appearance and, crucially, in the colour of froglight they generate. Temperate frogs are based on the brown bullfrog and spawn naturally in swamps and mangrove swamps. Warm frogs are based on the grey foam-nest tree frog and appear in warm biomes such as mangrove swamps. Cold frogs do not spawn deep inside cold biomes on their own, but they can spawn in a swamp or mangrove swamp that borders a cold biome.
Here is the key mechanic that trips most players up: an adult frog’s variant is locked, but it is not inherited. The variant is determined entirely by the biome in which a tadpole grows into a frog, regardless of what variant its parents were. That means you can take any two frogs you find, breed them anywhere, and steer the offspring toward whichever variant you want simply by choosing where the tadpoles mature.
Breeding frogs with slimeballs
The breeding food for frogs is the slimeball. Hold a slimeball and any frog within 6 blocks will follow you, which makes herding them into a pen straightforward. Feed a slimeball to two adult frogs and they enter love mode. Rather than dropping a baby directly, one of the two frogs becomes “pregnant,” similar to turtles. That frog then travels to the nearest water source (or waterlogged block) with air above it and lays a block of frogspawn on the surface. Successful breeding also awards a small amount of experience.
You can gather slimeballs in two convenient ways that pair nicely with frogs: kill slimes (frogs themselves attack and eat small slimes, dropping slimeballs), or farm them in slime chunks and swamps at night. Because frogs consume small slimes, a frog pen near a slime farm becomes partly self-sustaining for breeding fuel.
Frogspawn and tadpoles
Frogspawn is the egg block laid on top of water. After a randomised delay of roughly 3 to 10 minutes, the frogspawn hatches into 2 to 5 tadpoles. Tadpoles are aquatic and will suffocate if left out of water, so keep them in a pond or pick them up. You can scoop a tadpole into a bucket of water, just like a fish or axolotl, and its age and custom name are preserved when bucketed. This is the easiest way to relocate a tadpole to the exact biome you need for the variant you want.
A tadpole takes one full Minecraft day, about 20 minutes of real time, to grow into a frog. You can speed this up by feeding it slimeballs; each slimeball reduces the remaining growth time by 10%. When the tadpole matures, the biome it is standing in at that moment decides its variant. Mature it in a warm biome for a warm frog, a cold biome for a cold frog, or a temperate biome for a temperate frog.
Variant, biome, and froglight colour
Each frog variant produces exactly one froglight colour when it eats a small magma cube. Use the table below to plan which biome to raise your tadpoles in based on the froglight you are after. The biome examples are representative of each temperature band rather than an exhaustive list.
| Frog variant | Mature tadpole in (example biomes) | Froglight produced |
|---|---|---|
| Temperate | Plains, forest, river, swamp, taiga | Ochre Froglight |
| Warm | Desert, jungle, savanna, badlands, mangrove swamp | Pearlescent Froglight |
| Cold | Snowy plains, snowy slopes, ice spikes, frozen river | Verdant Froglight |
How frogs make froglights
Froglights are the only block in this chain you cannot craft. They are obtained exclusively when a frog eats a magma cube of the smallest size. Magma cubes spawn in the Nether in large, medium, and small sizes; when killed, larger cubes split into smaller ones, and only the smallest “small” magma cube can be devoured by a frog. When a frog flicks out its tongue and eats one, it drops a froglight whose colour matches the frog’s variant.
To farm them, you generally lure or transport frogs to a controlled spot, channel small magma cubes (split down from larger ones) toward the frogs, and collect the froglights that drop. The payoff is worth the effort: a froglight emits light level 15, the maximum possible for any block, so it doubles as the brightest decorative lighting in the game. Froglights also give off a little heat, melting nearby snow and ice.
For reference, froglights and the frog rework arrived with the Wild Update in Java Edition 1.19 and Bedrock Edition 1.18.10. The temperature-variant behaviour described here matches current versions; older clips may show the legacy white/green/tropical-style frogs that predate the final naming.
Frequently asked questions
Does the parent frog’s colour decide the baby’s colour?
No. A frog’s variant is set when its tadpole matures, based on the biome the tadpole is in at that moment, completely independent of the parents’ variants. You can breed two temperate frogs and still raise a warm or cold offspring just by maturing the tadpole in the right biome.
Can I get froglights without going to the Nether?
Not in survival. Froglights only drop when a frog eats a small magma cube, and magma cubes spawn in the Nether. You will need to either bring magma cubes back to your frogs or farm them where they spawn.
What do I feed tadpoles to grow them faster?
Slimeballs. Feeding a slimeball to a tadpole reduces its remaining growth time by 10% each time, so a handful of slimeballs can turn a 20-minute wait into a quick mature.
Keep exploring
Frog farms and froglight collections are far more fun to build with friends, and spinning up a private Minecraft world to share with your group means your tadpole ponds and Nether farms keep ticking even when you log off. If you want help getting set up, the Minecraft server documentation covers the essentials.
