Steal An Egg On KuKirin Rarest Eggs: Verified Egg Tiers

The short answer: Steal An Egg On KuKirin does not, in anything players can actually verify in-game, crown a single "rarest egg." What it clearly does mark are five exceptional egg types — epic eternal, legendary, mythical, secret and cosmic eggs — and the comparisons confirmed during real play support exactly one order: mythical > legendary > epic. Secret eggs behave like the top prize (players hide them from each other, and the run's narration calls them "hard to get"), while the cosmic egg is a confirmed type with no ranking statement attached at all. Below: how the game flags rare eggs, what each type looked like in play, how far the ranking honestly goes, and how to judge your own pulls.

What "rare" means in Steal An Egg On KuKirin

Rarity is the point of the whole loop. You ride the KuKirin, steal eggs out from under angry dinosaurs, and hatch them to collect rarer and rarer pets — a fan-made overview of the game describes exactly that progression, with pets, sizes and mutations as the things to discover. New pets pay you back, too: "When you get a new pet, it gives you speed and cash," which funds better bikes and deeper raids toward rarer eggs. A rare egg matters because of the pet that hatches out of it.

In one recorded play session, players flagged exceptional eggs using six recurring signals:

• Tier names read or called out in play: "epic eternal egg," "legendary," "mythical"/"mythic," "secret," "cosmic."
• Drop percentages shown on hatched pets: one player bought extra eggs "because I want to drop the 1% one"; another settled for "a 24% Velicoraptor." The lower the share, the more a pull is worth chasing.
• Visual cues: "there's a glowing egg in the shop," "there's a big egg here that's rare," "some golden one with a witch's hat."
• Egg weight, cited while sizing up a fresh steal: "39 kg" on the epic eternal egg, "50 kilos it weighs" on a bull egg.
• Per-second cash income revealed once the pet hatches: weak pulls earned 60, 315 and 11,000 ("what a bummer"), while better ones hit 50,000 ("already pretty good") and 220,000 ("How is that earning you so much?").
• Plain difficulty statements, like "it's hard to get a secret."

One honesty note before going further: these observations come from a single session's auto-captured commentary, so spellings appear as captured ("Velicoraptor"), and it isn't always clear whether a cue like the shop glow is an on-screen label or just the players talking. The tier names themselves, though, recur across the whole run. The cash figures are also one session's numbers on specific pets — treat them as a scale, not fixed rates. The percentages only show up once a pet hatches; the basics of that process are covered in how to hatch eggs.

The rare eggs the game actually names

Five types got named during play, and they don't all fill the same role:

The roles are distinct. Legendary is the mid-game workhorse: tied to stage levels, gated by cash amounts, and stolen deliberately as an upgrade ("I hope it will earn well"). Mythical is the chase target — announced by countdown, guarded by the clown, celebrated when it finally drops. Secret is the social prize: owning one is something you conceal, owners get chased across the map ("he ran away from me. He's too fast"), one player skipped a steal outright — "there's a secret here, but I won't steal it" — and later grumbled that "the secret would have come in handy." Cosmic is simply a confirmed kind; treat any assumption that it outranks mythical as a guess.

How far the ranking actually goes

Three comparisons were verified in play, and they stack neatly:

1. Legendary beats epic. A player guessed "An epic is probably better than a legendary," got corrected mid-run — "no, a legendary is better" — and accepted it: "okay, that's good to know."
2. Mythical beats legendary, "and by a lot." Confirmed while chasing the clown's mythical egg: "It's better than the legendary one." "And by a lot."
3. Cash income matches the order. Pulls earning 315 and 11,000 per second drew "what a bummer," 50,000 was "already pretty good," and 220,000 earned a disbelieving "How is that earning you so much?"

• Verified order: Mythical > Legendary > Epic eternal
• Unplaced: Secret (most coveted, "hard to get"), Cosmic (no data), and the unnamed 1% pull

That's where it stops. Nothing compares secret against mythical or cosmic, the cosmic egg never gets a quality statement, and the 1% pet the players chased is never named — so the lowest observed rate can't be pinned on any egg. The session's own video title says "rarest eggs," but a title isn't in-game proof. On current evidence, calling any one egg the game's rarest would be a guess; the honest ceiling is the partial order above.

How to judge your own eggs

When you hatch or steal, you can run the same checks the players did:

1. Read the tier name on the egg or the pet card.
2. Check the drop percentage on the hatch — a lower share means a rarer pull, as the gap between the chased 1% and the shrugged-off 24% shows.
3. Watch the per-second income on the hatch and compare it to the session's scale: hundreds or low thousands were bummers; tens of thousands and up drew excitement.
4. Note the secondary flags — weight, glow, sheer size, special skins.
5. Recheck the labels after patches; rarity presentation can move with updates, so glance at the game's updates before trusting an old ordering.

Rare target first, unlock second

Knowing which eggs are rare is not the same as knowing how to get one — nothing observed here ties a rarity label to its unlock requirements, so don't treat "mythical" as a recipe.
