You can run this command in the overworld to summon a baby zoglin
/summon minecraft:hoglin ~ ~ ~ {Age:-32767,TimeInOverworld:1000}
Then you can set gamemode to survive, the baby zoglin will attack you, and it will deal the same damage like adult zoglins while it attacks faster than any other melee mobs.
Duplicate of MC-177997. Baby zoglins' attack is much faster is intended, but the damage isn't, see MC-177997.
Baby hoglins for example attack faster but does not do any damage.
