I think you meant possums and not sloths, though both have different bone structures than ours.

Overall, I think it worked well to play off the style of the seed sentence but not overdo it and wind up evoking a feeling by the end of it.

Some effective impressionistic writing, though I think that the implied jocularity of the seed sentence is lost a little in the rest of the piece. Still, a good stab at the challenge.
