I can answer that for you. You can get the egg and the other stuff into your siggy by copying it from the PM Light Azumarill sent you and then pasting it into your signature. Also, I'm sure you can see that there are no Squirtle eggs available (This is the second time you ask for something that isn't on the list. Please, the rules aren't really that complicated and the list is right there. I'm assuming that you're litterate). So if you want a Squirtle egg you will either have to chance it by choosing a random pok?mon egg (Which can be any first-stage, so it's not a very good option) or then you could just adopt the Squirtle right there, no need to go through the egg phase.
