A statement piece.

I couldn't help but notice some similarities between River's sculpture and The Great Wave.  Perhaps using critical care as her medium is a commentary on the inexorable forces she struggles against whenever she refuses solid food and requires force-feeding.

Bunny care tip:  You can form a critical care log using 10g critical care powder and 15g warm water.  It'll be solid enough to form into a wedge shape that's a bit easier for them to eat...unless they decide to stomp on it like River did to create her artwork.
