Slugs do drastically change.

The one on the left was laid about an hour before the one on the right, so you can already see how much it changed. Also, when I removed the eggs to take to the incubator, I also removed the slugs I put them in an empty container to dispose of later. Well, I forgot to dispose of them.
I came back later and they had deflated, changed shape completely, and started oozing out greasy, oily, waxy stuff.
Glad your girl got all of them out!
I'll keep my fingers crossed for you next year!
