I agree - pacifier addict, which is Rearz. That's their size 6 adult pacifier, with a print on it - but you can customize them, so it may be something someone ordered, rather than something they list.
I was going to get one with a Pampers logo on it when I was there in person a couple of years ago, but whereas the pacifier costs like $5, adding the print brought it up to $20 or something... not worth it to me. I have like 25 of them already. But if you find that image and go to them with it, they can make that for you.
I've found this with Rearz' large-sized newer products. I moved to the XL in some models, even though by waist size, I could still theoretically wear a medium. The size of my legs makes the lower taps barely reach the front, which is more of an issue with hook/loop fasteners, because if you don't overlap that mesh, you're toast, unless you use a mechanical fastener like a pin or a staple. I'm in a Mega Barnyard right now in size Large, and the lower tabs are only half on the mesh. Granted, they are staying put - I slept in it as well and none of them came off - but the next size up would be a better fit. Whereas I can still wear a medium MegaMax, and an XL MegaMax would go to my chest and be visible from space.
