Lil Guy

Named baby animals will never grow up! Similar to Golden Danelions, they will stay babies forever.
"Naming" a named entity with an Unnamed NameTag will Unname the entity; this can be used to allow a baby mob to grow (though, they're vulnerable to despawning).
This mod was inspired by Scotty!
A sever I played on had a feature for keeping animals as babies but it did not work.
Scotty is fine but I wanted a reliable way to have this functionality.
