As a 5 month old naked baby you're kind of at the man's mercy at this point as he carries you away from the fountain leaving behind your clothing. You wonder where you're being taken too, but you can't really speak and aren't really strong enough to resist so you just rest for now and allow yourself to be taken along for the ride.
Eventually, you arrive at an orphanage, inside the zoo.
"Ohhhh, do we have another one?" It was a kindly woman's voice that spoke, but as you turned your little head what you saw instead was a kangaroo. Looking down at her, you could see two other human children, neither one older than two and both naked sleeping inside her pouch.
"This one was older, but they jumped into the fountain when I found them." The man handed you over to the kangaroo.
"That's okay. The littler they are when they come in the faster they get adopted. Thank you very much." She cradled you in her warm furry arms before hopping into another room. You were able to look around seeing the rest of the orphanage in the process. There were plenty of kids, and from the previous conversation you could guess they had all used the fountain of youth. Most of them were completely naked, though a few still had on shirts that were several sizes to large.
Eventually, the kangaroo lady places you in a cradle inside a nursery room. There is a lullaby playing in the background, and before you can take in to much more of your surroundings you find yourself slowly nodding off to sleep.
The last words you remember were
"Don't worry, we'll find a new home for you."
