On the building instructions page of the LEGO website, there are two upcoming first images of the square head boy, 40559 BB Bird and Crooked Wolf and 40549 Demon King (Demogorgon) and Eleven, which are from the "Le Yi Tong" and "Stranger Things" themes, respectively.
While no listing date has been announced yet, given that the official charts are out, they are expected to be released in February or March, while they are priced at $19.99 according to previous rumors.
The LEGO Group did not choose Bugs Bunny and Duffy Duck in the first Legi Pass Square Head Boy, but chose a pair of sworn enemies, BB Bird and Crooked Heart Wolf, which still look a little cute, but the Crooked Heart Wolf looks a lot fatter.
Recently, 75810 Stranger Things - Upside Down Worlds should have been on the road to discontinuation, and this 40549 Demon King (Demogorgon) and Eleven inherited its theme, providing a choice of Stranger Things before the fourth season of the episode aired.
These two square heads have a lot of patterns, especially the devil king's teeth, but they should look like stickers.
