New mob in the swmp

Hello Mojang! I am a Korean player who loves Minecraft. I propose a new wild update that adds realistic and unique animal behaviors to the Overworld. SWAMP Catfish: Large fish scoopable with a bucket. Harvesting them yields Catfish Whiskers, which craft directly into String (useful for Peaceful mode). Cooked Catfish gives high hunger saturation. Salamander: The Axolotl of the swamp. They have muddy-brown skin and can walk on Mud blocks without drying out.
