I don't think a pouch or egg is a good fit for the game. Something to potentially look forward to for next update though, is that it will have an event I've labelled 'Reminisce'. It won't be nearly as rare as 1/1000, but if you control Amelia and have her behave a certain way with predators, she will periodically chime in separately from everything else happening. If she spends enough time with a predator, she will remember how that time went. If it was largely unwilling, she will have some sour comments to make about her situation or at the start of the encounter if they meet up again. If she's willing, she will have favorable things to say, and may even daydream about visiting a particular predator she had the best time with if she spends too much time not as their prey. There is more to it, but I think it will spice up some of the repetitive points in the game.
