I add the Crab to Minecraft
Demonstration video of the datapack: https://youtu.be/ppfzhSp3jqc
This datapack adds crabs to the game that spawn in mangrove swamps. For every two frogs in this biome, one crab will be generated.
The feature of the modification is the crab claw - a special item that, when placed in the character's off-hand, increases building reach by three additional blocks. This allows building and placing blocks at a greater distance, which significantly simplifies the creation of large-scale structures.
