Impossible Animals Eggs List: 5 Documented Egg Entries

The five egg entries documented in Impossible Animals, with verified hatch bands, observed results, hatch times, and the pen rules every egg followed in play.

Five egg entries have been documented in Impossible Animals so far: the Common Egg, the Epic Egg, a common diamond egg, a normal egg, and an 11-star egg. Every entry below carries at least one recorded fact, whether that is where it came from, how it behaved in the pen, or what hatched out of it. No available source enumerates a full egg roster, so this page claims exactly those five entries and nothing more.

Eggs are not a community rumor, either. The game's official How to Play text lists "Collect and hatch eggs to discover rare hybrids" alongside fusing animals, treadmill training, and battling through The Wild.

How entries get onto this list

An egg only appears here if recorded play of this exact game names or visibly rates it. Three kinds of identification show up, and they are not interchangeable:

Tier names. The Common Egg and Epic Egg are named in recordings of play, each with a hatch band: 3–5★ when hatched for the Common Egg, 9–11★ for the Epic Egg.
On-screen labels. One session shows two eggs named directly as a common diamond egg and a normal egg.
Star counts. An egg can be identifiable by rating alone. One battle reward was taken purely as "an 11-star egg," with no tier label shown at all.

Nothing recorded so far names a third tier, so none are listed. If a newly captured hatch documents another egg, it gets added here.

The five documented eggs at a glance

Egg entry	How it is identified	Where the observed one came from	Observed result
Common Egg	Tier name in recordings; the stage-reward egg is labeled "a common-level egg" on screen	Post-stage reward, offered among three options	3–5★ hatch band; one opened into a wolf-monkey in 17 seconds
Epic Egg	Tier name in recordings	Not shown being acquired	9–11★ when hatched (band only, no hatch captured)
Common diamond egg	On-screen label, shown beside a normal egg	The fight/jungle area ("here you can get an egg too")	First of the pair to open hatched a cheetacrab
Normal egg	On-screen label, shown beside the common diamond egg	The fight/jungle area	Second to open hatched an 8-star tricertank
11-star egg	Star count at a battle reward; no tier label shown	Post-battle reward choice	Opened after about a minute and a half into a dragonfly-human

Observed hatch outcomes, entry by entry

Common Egg ("a common-level egg" on screen)

The reward egg captured in play is earned by fighting: "Basically, if we beat a stage, we get one reward," and the player chooses from three options. "This one is an egg—oh, I'll take the egg." The same player adds a scaling note worth knowing: "The rewards get better as the stages get harder."

This egg "takes 17 seconds to open," and hatching is completely hands-off. The game fuses the parents itself: "Oh, it fuses them for us, guys. This is a monkey mixed with a wolf. A wolf-monkey." Recordings give the Common Egg a hatch band of 3–5★.

One loose end sits outside that band. The same player mentions, second-hand, that a friend's egg hatched "like 10 stars. 10 stars, everyone. A T-Rex mixed with a tank." That hatch never appears on screen, so it stays an unconfirmed report. It is not counted as a verified Common Egg outcome here, and nothing shows it was even the same tier.

Epic Egg

The Epic Egg is the only other named tier on record. Recordings give it a 9–11★ hatch band when hatched, and no Epic Egg hatch was captured in the material behind this list, so no specific result or open time is attached to the entry. The strongest documented hatch in play remains the 11-star dragonfly-human below.

Common diamond egg and normal egg

One session picks eggs up around the fight/jungle area: "Here we unlock the animals. And here you can get an egg too. We got an egg." The player then sets both at once: "I put both eggs to hatch. We have a common diamond egg and a normal egg."

The first to open, the one the player expected to be the common egg, produced a cheetacrab (cheetah + crab). The second produced "an eight-star tricertank, meaning a tank plus a triceratops."

One attribution caveat matters if you are comparing results: the game does not label the placed eggs on screen, so which name belonged to which physical egg is inferred from the order the player expected them to hatch. It is also not established whether the common diamond egg is its own tier or a variant of the Common Egg; nothing recorded settles that.

The session's own takeaway frames your real choice: "you can get animals with eggs or you can make your own fusion." Eggs hand you a finished hybrid; if you would rather pick the parents yourself, that is what manual fusion is for.

11-star egg

A later battle reward was identified by rating alone: "This is an 11-star egg, but it comes pre-fused, I don't even know what it is. I'll take it, it only takes a minute and a half." That is a much longer countdown than the 17-second common-level egg, and the payoff matched the wait: a dragonfly-human the player immediately ranked above everything he owned. "It's even stronger than this one, guys. It's more powerful than this one."

Its 11-star rating sits inside the recorded Epic band of 9–11★, but the video never shows a tier label on the egg itself, so calling it an Epic Egg would be a guess.

Rules every documented egg followed

An egg takes a pen slot. With the pen full, nothing can be placed until you clear room: "our slots are already full. So I'll have to remove some animals from here. Only then can the egg be placed." The player removed a four-star animal and the egg slotted in. The pen holds five creatures and includes a designated egg area ("Here is where the eggs stay"). More on the layout is in the pen guide.
Hatching runs on a visible countdown. Placed eggs open on a timer. The only two times captured are 17 seconds for the common-level egg and about a minute and a half for the 11-star egg, so treat both as single observations, not per-tier rules.
Two eggs can hatch at the same time. The common diamond egg and the normal egg were placed together and opened one after the other.
The Wild also drops eggs on the ground. Beyond reward choices and the fight area, one player simply grabs one mid-run: "I picked up the egg from here."

One rule covers the result itself: you never pick what comes out. Every documented egg hatched a pre-fused creature the game chose, with the players reacting to each reveal only after it opened.

What this list cannot tell you yet

Roster completeness. These five entries are what recorded play has shown. This page does not claim the game contains only these eggs.
Costs and odds. Nothing recorded shows what any egg costs or the chance of hatching any particular creature or star value.
Hatch times per tier. Two opens were timed (17 seconds; about 90 seconds). More observations would be needed before either becomes a rule of thumb.

Where to go next

If you need more eggs, the acquisition routes above are covered step by step in the how to get eggs guide. If one is already sitting in your pen, the how to hatch eggs guide takes over from placement to open.
