Frog

Frog is a passive mob found in swamps. It eats small slimes and small magma cubes, making it useful for farming slimeballs and unique light-emitting blocks called froglights. The type of Frog is determined by its spawn biome, and each type produces a different froglight when eating a magma cube. Frog does not drop any items when killed. Frog can be bred using slimeballs. When two Frog are fed slimeballs, they enter love mode, and one becomes pregnant. The pregnant Frog searches for a water block with at least one adjacent water block and lays frogspawn. The frogspawn hatches into tadpoles, which later grow into Frog. Unlike other baby mobs, tadpoles are considered a separate entity from Frog.

Frog attacks using its tongue, instantly pulling in and despawning small slimes and small magma cubes. When Frog eats a small slime, it causes the slime to drop slimeballs. When Frog eats a small magma cube, it produces a froglight block. The color of the froglight depends on the Frog type. A temperate Frog found in normal swamp biomes produces Ochre Froglight. A warm-climate Frog, which is typically white, produces Pearlescent Froglight. A cold-climate Frog, which is green, produces Verdant Froglight.

Frog follows any player holding a slimeball within six blocks and can be leashed using a lead. Its ability to produce froglights and help farm slimeballs makes it useful for farming and decoration.
