One more "That's a bowling ball" here. For one thing, the two close together eyes and one separated one are characteristic of a bowling ball - but a coconut has its eyes almost equidistant. And they are shallow depressions not deep holes to stick your fingers in. (And I don't think I've bowled in the last eight years).

It's a pretty lousy cartoon. But it's not a subtle one. And there is a certain point beyond which you can say that things are being read into a text due to the prejudices of the external observer rather than due to the text. I don't know whether this hits that line, but it comes remarkably close. (Actually it's a matter of cultural knowledge and lack of it here.)
