I know babies can come in a barrel or a crate and I thought I heard something about a chest. Is it correct that there is one baby in the chest, two or three in the barrel and four in the crate? Or do they vary? And if you get several toddlers in an event, will they all be the same age, or can you get two two-year-olds and two four-year olds? And what's the oldest child you get in these events?
