Awh but is so easy! You just gotta put -> : iconsoaparthurplz : without the spaces! And that goes with everything else actually. :3c You just have to put the word 'icon' at the start of it and -almost all of them- the plz at the end! Look through different icons around and there you go! Have an example; See? You just have to put the name of the devUser in the middle : icon : Was that good enough of an explanation? <:3c
There are A LOT of icons out there! Most of the time, when you find an account on dA that ends with 'plz' is probably because that's used as an icon.
