This is a project which takes place on the DC forums. Their aim is to get one egg to be passed onto as many scrolls as possible before it grows up. The first egg they did it to was a pebble (chosen because of how common it was, making it less likely to be sniped during scroll moves).
The first round lasted from the 6th to 9th of July, 2009. Before being lost in transfer, it visited 24 scrolls.
