The ducks seemed to think it was pretty terrific because they would dig their bills into it and jab up and down until they scored a tasty treat. The other birds were light weight enough they didn't sink. It was actually rather springy and sometimes I could even hear a slosh when I stepped. It wasn't a horrific problem unless I stepped in an especially wet area hidden beneath the paper mache mud. Then, it was like walking along in crunchy snow and suddenly losing a leg down into a snow drift.
Except it wasn't snow and I had holes in my rubber boots.
