Froglight

Java

A froglight is a natural block that can be obtained if a frog eats a magma cube.

Obtaining
When killed by a frog, a magma cube drops a froglight. There are three variants of froglight that drop depending on what type of frog kills the magma cube: pearlescent (purple) from tropical frogs, verdant (green) from snowy frogs, and ochre (yellow) from swamp frogs.

It is the only farmable block that neither has a crafting recipe nor naturally generates in the world.

Light
Froglights emit a light level of 15, the highest level in the game, similar to the Sea Lantern.
