Penguins look harmless/inoffensive/easygoing/mild.

Are all of the underlined words pretty much the same in the above? Thanks.

No: harmless and inoffensive are objective and appropriate in this zoological context. Easygoing and mild are better when used of me rather than of penguins.

Thanks, Mister.

To make sure, do you suggest that easygoing and mild apply better to human beings while the other two animals?
Generally yes, unless anthropomorphizing.
Thanks, Mister.

Got it!
