This advert in the Beano, 5th January 1991, explains the promotion fully:
"FREE 2 in 1 Mutagenic Sticker and Transfers INSIDE every Frosted, Original and Coco SHREDDIES Packs"
This 2-in-1 sticker/transfer technology was used previously for the Trio Roland Rat promotion of 1987, & frankly it didn't work then.
You can see the problem for yourself: you're looking at the underside of the transfers, which are backed by opaque card (which the sticker was attached to), rather than transparent plastic; you can't see through the card, so you can't see where you're going to apply your transfers. Guesswork is the last thing you want with transfers, since you don't get a second chance!
Bottom: with backing tissues still in place; Top: without backing tissue
Now is the time to mention the Acorn logo, which despite denials, must surely signify that Acorn printed these sticker/transfers. We haven't seen this logo often; on the Roland Rat sticker/transfers mentioned above, & on the Katy No.1 Free Gift… that seems about it.
The stickers are fine, however. It's just the "2-in-1" gimmick that doesn't fly.
There were six sticker/transfers, & four different background scenes on packet backs.

Okay — that was a packet front. Here are the backs, all of them courtesy of the ever-helpful Nick Symes:
"The Dudes' Southside Den"
"The New York Roof Top Scene"
"Face to face in the Antique Shop"
"Open Combat in the streets of New York!" — Scans courtesy of Nick Symes
You could also send off for a FREE 'Mutagenic' glow-in-the-dark poster on which to apply your stickers. I'm not sure describing it as 'FREE' was entirely fair, since you had to enclose eight special tokens & 50p ("for postage and packing").
The special tokens, though; where are these special tokens? Do they mean the Acorn logos? Are they on the top of the box, & not included in Nick's scans? Where are the tokens, Nick?
