In Minecraft 1.19, frogs can eat small magma cubes, small slimes, and slimeballs. If a small slime or a small magma cube comes close to a frog, the frog will eat it immediately. Meanwhile, you can feed slimeballs to a frog by right-clicking or using the secondary action key while holding a slimeball. If a frog eats a small slime, it drops slimeballs that can later be fed to the frogs. However, on eating a magma cube, the frogs drop a froglight, which is a light block with the same color as the frog that dropped it. There is no recipe in the game that involves frog lights yet. To breed frogs, you can feed them slimeballs, and they will enter Love Mode. After some time, tadpoles will hatch in groups of two to five.
