This mod adds dynamic name tags to certain named mobs.
For example, naming a mob "Dinnerbone" or "Grumm" also causes its name to be upside down. Naming a sheep "jeb_" makes its name cycle through the sheep colors.
A vindicator named "Johnny," for instance, has a red name, since naming a vindicator "Johnny" makes it attack any entities (except evokers, pillagers, other vindicators, and ghasts).

This mod does not add any items, blocks or entities; it is client-side only. There is no need to install it in a server.
It also has no dependencies, not even Fabric API.
For mod/data pack developers
Creating a dynamic name tag is very simple.
