can someone make a world (in vrchat) different deers or an idea someone made an anime girl/boy with a hoodie of their deer (somewhat like a pikachu hoodie, seen around) that'll be super cool!

ok my deer & I saw a deer with a mask we both never see before it is orange mask that looks like a super hero mask of some sort. is it rare? how you manage to get it? isn't there another mask simular to it but blue color?
