I mean hell, normal eggs [i]never[/i] clean themselves at all! The fact that Mamoru's does ought to make her eggs quiet popular for people who want clean eggs.

Though now I'm just imagining a twisted sort of sales scheme where Mamoru and Kath are selling their eggs to new worlders. Alternatively, Mamoru convincing Rodias and some of the other Chapter Masters to make a sort of pen house for Mamoru's clones to just lounge about and lay eggs. That'll be a dream job.
