Froglights in Minecraft Bedrock: How to Get the Exact Color You Want

You bred two frogs, waited for the tadpoles, fed a magma cube to the grown-up, and got a froglight in completely the wrong color. So you tried again with different frogs, and got the same wrong color. Frustrating, right?

Here's the secret nobody makes obvious: the color has nothing to do with the frogs you bred, and nothing to do with their parents. A froglight's color is decided by the biome where the tadpole grows up into an adult. Get that one rule right and you can produce any of the three colors on demand.

The One Rule That Controls Everything

There are three frog variants, and each one makes a different froglight when it eats a small magma cube:

Temperate frog (orange) makes Ochre Froglight (yellow).
Warm frog (white) makes Pearlescent Froglight (pinkish purple).
Cold frog (green) makes Verdant Froglight (green).

And the variant a tadpole becomes is set by the biome it's standing in the moment it matures. Not the parents, not where the frogspawn was laid, not where you did the breeding. Just the maturing biome. That means you can grab any two frogs, breed them anywhere, and steer the babies to whatever color you want by raising the tadpoles in the right place.

Which Biome for Which Color

Pick your froglight, then raise the tadpole in one of these biomes:

Ochre (yellow): temperate frog. Raise in a mild biome: swamp, plains, most forests, taiga, meadows. This is the easy one, since temperate frogs already spawn naturally in regular swamps. You may have them without doing anything.
Pearlescent (purple): warm frog. Raise in a hot biome: desert, jungle, badlands, savanna, mangrove swamp, or any Nether biome. Warm frogs spawn naturally in mangrove swamps. Handy trick: since you'll be in the Nether for magma cubes anyway, drop a tadpole into a little water pool there and it'll grow into a warm frog on its own.
Verdant (green): cold frog. Raise in a cold biome: snowy plains, snowy taiga, grove, frozen peaks, jagged peaks, the deep dark, or the End. This is the tricky one, because cold frogs do not spawn naturally. The only way to get one is to raise a tadpole in a cold biome yourself.

Step by Step: From Frogs to the Color You Want

Find two frogs. They spawn in groups of two to five in swamps and mangrove swamps. Hold a slimeball and they'll follow you within about 6 blocks, so herding a pair together is easy (leads work too).
Breed them. Feed a slimeball to each frog. They enter love mode, and instead of a baby appearing on the spot, one frog hops to the nearest water and lays a block of frogspawn on the surface.
Wait for tadpoles. The frogspawn hatches after about 10 minutes into a handful of tadpoles.
Bucket a tadpole. Use a water bucket on a tadpole to pick it up, exactly like scooping a fish. Now you can carry it anywhere.
Take it to the right biome. Travel to the biome that matches the froglight you want, and pour the tadpole into a bit of water there.
Let it grow up in that biome. A tadpole takes about 20 minutes (one full Minecraft day) to mature. You can speed this up with slimeballs: each one you feed cuts 10% off the remaining time. The instant it becomes an adult in that biome, its variant locks in.

Important: the variant locks at the moment of maturing. Moving a grown frog to a different biome afterward does nothing. If you want a green frog, the tadpole has to finish growing while it's sitting in that snowy biome.

Actually Making the Froglights

Once you've got a frog of the right variant, you need small magma cubes for it to eat.

Froglights only drop when a frog eats a small magma cube. Medium and large ones are too big for a frog to grab.
Magma cubes spawn in the Nether, and they're thickest in basalt deltas. Large ones split into smaller ones when hit, so you can farm the small size from bigger spawns.
Get a small magma cube next to your frog. It hops over, flicks out its tongue, and the magma cube is replaced by a froglight block that you can mine and place wherever you like.

Froglights can't be crafted, so this is the only way to get them. They're worth the effort: each one is a full-brightness light source (light level 15) that looks fantastic in builds.

Bedrock Notes

Good news for once: the frog and froglight system works almost identically on Bedrock and Java, so most guides you find will be broadly correct here. A few things are still worth knowing as a Bedrock player:

The "When the Frogs Come Home" reward is Java-only. Plenty of guides tell you to collect all three frog variants for that advancement. It's a Java advancement, so you won't find a matching entry in your Bedrock achievements list. Don't go hunting for it.
Biome temperature is defined a little differently under the hood between editions. The practical effect is tiny, but to avoid surprises, raise tadpoles in an unambiguous biome. A proper snowy biome for green, a desert or the Nether for purple, and a swamp or plains for yellow will never let you down. Borderline or transitional biomes are where the occasional "wrong color" story comes from.
Only tadpoles go in buckets, not adult frogs. So plan your color before the tadpole grows up. Once it's an adult, you can't scoop it and try a different biome.

If you'd like a world where a swamp sits close to both a snowy biome and a desert (ideal for farming all three colors without long trips), it's worth browsing a few Bedrock seeds before you start.

Troubleshooting

"My tadpole grew into the wrong color." It matured in the wrong biome, or in a biome whose temperature classification isn't what you expected. Bucket the next tadpole and make sure it finishes growing well inside a clearly warm, cold, or temperate biome, not near a border.

"My frog won't eat the magma cube." Check the size. Frogs can only eat the smallest magma cubes. If it's a medium or large one, hit it a couple of times to split it into small ones first. Also make sure the magma cube can actually reach the frog (no fence or block wall between them).

"I can't find any cold or warm frogs." That's expected. Only temperate (swamp) and warm (mangrove swamp) frogs spawn naturally. Cold frogs never spawn in the wild at all. Every cold frog in the game was raised from a tadpole in a cold biome, so you have to make them yourself. If you have cheats on and just need to locate the nearest snowy biome, /locate biome can point you there, though remember enabling cheats permanently disables achievements for that world.

"My frogspawn disappeared and never hatched." Frogspawn needs to stay on the surface of water. If the water below it is broken or the block is disturbed, it can pop off before hatching. Lay out a calm, undisturbed water surface and leave it alone for the ten minutes or so it takes to hatch.

Wrapping Up

Froglights feel fiddly until the rule clicks: the color comes from the biome where the tadpole grows up, full stop. Bucket a tadpole, walk it to a swamp for yellow, a desert or the Nether for purple, or a snowy biome for green, let it mature there, then feed the adult small magma cubes. Get that sequence down once and you've got a reliable supply of the best-looking light blocks in the game, in exactly the color your build needs.
