Minecraft wiki entry for Frog, associated text: The warm frog is based on the grey foam-nest tree frog, a real-life species of frog native to Africa.[1]
Despite the fact that swamps lost the Biome Vote in MINECON Live 2019 taking second place, frogs were implemented in the game three years later in Bedrock Edition and Java Edition.
Frogs were shown in Minecraft Live 2021 to enjoy jumping on big dripleaves.
Originally, frogs could eat fireflies, but this changed, as in real life fireflies are poisonous to frogs. Instead, now they can eat small slimes and small magma cubes.[2]
In Bedrock Edition, the fifth hurt sound of frogs is unused. However, it is used in Java.
At one point in Bedrock Edition's development, in beta 1.18.10.26, frogs can eat goats. However, it was later removed as it was a leftover prototype code.[3]
