About this project
What does Age Switch add?
This datapack adds a fun mechanic that lets you change a mob’s age using name tags. Renaming a mob as “Baby” transforms it into its baby form permanently, even if renamed again. The only way to reverse the effect is by using another name tag named “Adult.” Perfect for players who want to build farms, zoos, or simply add a more dynamic and adorable touch to their world.
