In the upcoming 1.19 Wild Update, a new block called the Froglight will be added. This new light source comes in three variants: the Verdant, Ochre and the Pearlescent. It can be obtained by bringing the new Frogs to the Nether, and then having the frogs kill Magma Cubes. The type of the froglight depends on the type of the frog that kills the Magma Cube. If you like an extra challenge, you can cut a hole in the paper and fit a light bulb inside. Have fun making these excellent lamps!
