Yellow Canary !

A yellow canary would be a great addition with the new huge caves players have to explore in 1.17! Canaries historically were used to check if mines were safe to go in. A canary could help lead the player to hidden rooms, dungeons, and chests in the caves. If you feed a canary a glow berry, it will lead you to the nearest chest, similar to how dolphins lead the player to the nearest underwater ruin when fed a cod. Or, the canary could sing/chirp a different "song" if you are close to something special in the caves (amethyst geode, warden, chest, etc). Canaries could spawn in forests to give some more life to forest biomes, and be tamed similar to parrots with seeds.
