This could also be a meta-commentary about how Street Fighter is carrying Capcom at the moment.
Street Fighter CARRYING Capcom? Try Monster Hunter. Street Fighter IV units sold: 9.8 million units Street Fighter V units sold: 7.4 million units Street Fither VI units sold (so far): 3.3 million units
Monster Hunter World (basegame) units sold: 20.1 million units. Monster Hunter World Iceborne (includes basegame) units sold: 25.3 million units. Monster Hunter Rise units sold: 14.7 million units Monster Hunter Rise Sunbreak DLC (not including basegame): 8 million units.
You can even check the official site for sales. So who's carrying whose now?
I wonder if this means going forward there will also be a golden mole hidden in each image.
No, they only appear (and not so hidden) in the next image afterwards.
The only "easter eggs" hidden in Zookeepers pictures will remain the (violent) duck, a doughnut stamp (a.k.a Donut boy) and sometimes (but not always) a seal handpuppet.
