When our kids were little, we holidayed at Mon Repos near Bundaberg to watch the annual turtle egg laying and hatching.
This model reminds me of the lovely little turtle hatchlings we watched, in the still of the night, emerge from their underground clutch and waddle clumsily towards the ocean. In truth they were about this size and sadly, only one or two of the entire clutch of hundreds of eggs will survive to adulthood.
Nice simple model, busy day, you can make one too: http://donyaquick.deviantart.com/gallery/?offset=24#/d224qix
