How Virtual Companions Work: Hatch, Feed & Grow Your Creature | CreatureLab

So you've been playing with the animal mixer and made some cool creatures. And then you saw that "Hatch as Companion" button and wondered what it actually does.
Short version: it turns your one-off creation into a virtual pet that grows over time. You feed it, it evolves, you get new images every time, and eventually you've got this whole visual growth story.
Here's exactly how it works, step by step.
The Daily Egg: Where Every Companion Starts
Every day you get one free egg. Just click the egg panel on the generator and hit claim — it picks two random animals from the catalog and gives you an egg with a rarity tier attached to it.
Rarity is just luck of the draw. Most eggs are Common or Rare. Sometimes you'll get an Epic. Legendary eggs are... well, legendary — don't count on seeing them every week.
The egg sits in your My Companions page as a little unhatched orb. You can only hold one unhatched egg at a time, so if you've already got one sitting there, hatch it before claiming the next day's.
One important thing: eggs don't stack. If you skip a day, you just miss that day's egg. There's no catch-up mechanic, so grab yours when you remember.
Hatching: The Fun Part
Hatching is free — no credits, no catch. You just open your egg and wait about 30 seconds while the AI generates your creature's first-ever image.
Before you hatch, there's a little text box. The game calls it a "spell," but really it's just a prompt. You can type something like "glowing antlers and a starry coat" or "looks like it lives in a volcano." Or you can leave it blank. Blank is fine — the AI will come up with something on its own.
I'd recommend writing something though. Even just three words. It makes the result feel more like yours.
Once the generation finishes, your companion gets its first image and officially exists. It starts at the Baby stage, and from here on out, everything is about feeding.
Feeding: Once a Day, Every Day
This is the main loop. You feed your companion, the AI generates a brand new image, and the new picture gets added to your Growth Album. Every feed changes how your creature looks — sometimes subtly, sometimes dramatically.
Feeding costs 5 credits. You get some free credits when you sign up, and you can buy more if you run out.
There's a daily limit — one feed per companion per day. I actually like this. It turns the whole thing into a little daily ritual instead of something you blow through in 10 minutes. Come back tomorrow, see what your creature looks like now.
The growth path
Three stages, and you need a certain number of feeds to move through them:
Baby — where everyone starts. After 3 feeds, it grows up.
Juvenile — the awkward teenage phase. 4 more feeds to reach adult.
Adult — fully grown. No feed cap anymore. You can keep feeding forever and every feed still makes a new image.
So minimum 7 feeds to go from a fresh hatch to an adult. If you're feeding daily, that's about a week.
The Growth Album
Every image from every feed gets saved into your companion's Growth Album. You'll find it on your companion's detail page, organized into three columns — Baby, Juvenile, Adult.
The album is honestly one of the best parts of the whole system. You can scroll through the images, compare how your creature looked at different stages, and see the visual progression over time. Each stage can hold multiple images, and you flip through them with the arrow buttons.
Clicking any image opens it full-screen with a download button. The images are high-res, so they're totally usable for wallpapers, reference art, whatever.
One small thing that's easy to miss: sometimes the AI attaches a little flavor message to a feed result. You'll see these as quote text in the album. They're randomly generated and add a bit of personality.
Making Videos from Stage Images
Any picture in your Growth Album can be turned into a short animated video. Look for the little film icon — it's on every stage image. Click it, pick your settings, and wait a minute or two.
Videos cost 10 credits by default. The result is a roughly 5-second clip that brings your creature to life. It's not Pixar-quality or anything, but for a social media post or just seeing your creation move, it's pretty neat.
You can regenerate as many times as you want. Don't like the first version? Hit regenerate and try again. Each attempt costs credits though, so maybe don't go crazy.
One thing worth knowing: the videos get saved permanently. Some sites store them on temporary URLs that expire after a day — we don't do that. Your videos stay accessible as long as your companion exists.
Naming, Sharing, and Showing Off
You can rename your companion anytime by clicking the name at the top of its page. Some people go descriptive ("StormWing"), some go silly ("Fluffy McNuggets"). No wrong answers.
There's a share toggle that puts your companion into the community feed. Other people can browse shared companions and like the ones they think are cool. It's low-pressure — no comments, just likes.
Each companion also gets a referral code. If someone signs up through your code, you earn some bonuses. Check the share section on your companion page for the details.
Rarity and Upgrades
Rarity comes in four flavors: Common, Rare, Epic, Legendary. It affects how your companion looks in the community feed more than anything mechanical.
You can upgrade rarity by spending credits. The costs:
Common → Rare: 50 credits
Rare → Epic: 100 credits
Epic → Legendary: 200 credits
Is it worth it? Depends. If you're putting your companion in the community feed a lot, higher rarity makes it stand out. If you're just collecting for yourself, probably not a priority. I'd spend credits on feeding and videos first.
Stuff people actually ask
Do I need to pay anything to start?
Nope. Egg claims are free, hatching is free. Feeding costs credits, but you start with enough free credits to feed several times.
What if I forget to feed for a few days?
Nothing happens. Your companion doesn't get sad, doesn't lose progress, doesn't degrade. Just pick up where you left off.
Can I have more than one?
Yeah, claim an egg every day and build a whole collection. I've seen people with 20+ companions. Each one grows independently.
Can I pick which animals go into the egg?
The daily egg is random. But when you create a hybrid in the generator and click "Hatch as Companion," that one uses the exact animal pair you chose.
What's the point of feeding after reaching Adult?
New images. Every feed still generates a unique picture, so your companion keeps visually evolving even after maxing out the growth stages.
Can I lose a companion?
No. Once hatched, it's yours permanently. There's no death mechanic, no expiration, nothing like that.
Should You Bother?
If you're just here to generate one-off images and download them, you can ignore the whole companion system entirely. The generator works fine without it.
But if you like the idea of having a little creature collection — something you check on once a day, watch grow, and build up over time — it's surprisingly addictive. The daily ritual is light enough that it doesn't feel like a chore, and the Growth Album gives you something concrete to look back on.
Start with the daily egg. It's free, takes 30 seconds, and you might end up with a companion you actually want to keep feeding.
