Looks like someone turned a bunch of characters into slugcats! The artist's interpretation of how slugcats look is admittedly more slug than cat. Caro is holding on with his bow onto something for dear life in the top left, under that is Vera Charon, who's behind the fat slugcat Cloud. He and Jade are having a staredown, as Sparrow hides behind Jade. Behind them, there's Spectre holding a sword that looks like a nail from hollow knight. Hawk is creepily slugging down an edge back there as well. And Draedon managed to invent something out of Iterator parts, a floating platform.

The characters are mine and the artist's.

Slugcat species is from Rainworld wich belongs to Videocult and Akupara games.
