That's probably a good idea as a general rule, yes.

Am now racking my brains to see if there is a non-offensive connotation of any of those as human descriptors and it's tricky. Hm. Maybe if someone applied it to themselves eg if someone says, "eek, I tried on a dress that made me look like a coconut, round and hairy!", which is daft but mostly lacks that, I think? Not sure. Anyway, the sheer difficulty of the exercise probably says something.
