piercings on fursuit

so my character has gauges and a tongue piercing, and im not quite sure how to go about it. (i unfortunately already cut out the holes in his ears for the gauges) so im not sure if i should try and find some that fit or what? if anything i'll just leave them open

but! the tongue piercing is where im having trouble. i don't know how i should go about making it/getting it to work?

heres the character: Image may be NSFW.
Clik here to view.
