That’s Kako with her head resting on Kazon.
Here, Kako is trying to engage her brother Kazon in a bit of play, something he promptly obliged her. By the way, that’s Grendel‘s post-surgery half-shaved ass you see in the lower-left corner of the photo. Similarly, Loki‘s paws are seen dangling from atop a cardboard box near the upper-right corner.
And to finish, that’s Kazon lying on top of the box with Kako on the floor beside it.
