In the lower horizontal strip, the Nile Festival Building is filled with scenes of animals attacking other animals.
Here in the lower left of the lower register two Panthers are each attacking two Deer. On the left edge, a Panther is attacking two mice, one of which is depicted as trying to escape off the left edge of the mosaic!
Note also the continuation of the "stream" that is flowing from right to left—evidently a branch of the Nile River.
