I like the idea of a rabbit, such a common symbol of fertility, presented with a collection, not of Easter eggs but of rocks (which of course cannot reproduce). And not “natural” rocks, but manuports.*
* Archaeologists use the term manuport for objects people have moved from their natural location, but otherwise have not modified them. These look like typical landscaping rocks sold by the 10- or 20-lb bag in big-box home improvement stores.
