this at first glance may be a invailed parity report

but.

the drowned in bedrock not only have larger heads but they also have larger arms
the larger head part is a dead give away of a second head layer but I have no idea whats with the arms.

you cant count the discountinued versions (like consle due to porting several bedrock features in a update)

screenshots will be provided as soon as i can

this oddity started right as drowned were implemented into bedrock
