How to draw OTM gags on Poly and Eddie

Many people with who I was doing art trades and I requested of Poly OTM gagged didn't do that and instead of this they drew another kind of gag, probably beacuse they didn't know how to draw the requested type of gag on a beak. So this pic is some kind of reference how OTM gag on Poly's beak SHOULD look like. Also here is Eddie whose snout is tricky to draw OTM gag on it, so it is also a reference.
