My entry for the Reaper Challenge League Q2 diorama:

The minis are:

Reaper Bones Black 44044 Dark Watcher as Pac Man
Reaper Metal 03920 Shadowgaunt as Pinky

Midlam Miniatures’ metal “Ghosts of Midlam Manor” x 3 as Inky, Blinky, and Clyde -the latter pair in edible mode.

and 3D printed walls designed by Printable Scenery
White balls are expanded polystyrene, plucked from some packing material. The Black gravel is …black gravel.

This is an idea I have had for a scene or diorama for ages, a Beholder stuck in a dungeon getting really bored, chasing the other denizens around playing tag, occasionally getting the munchies.
