Snacks & Growth

Snacks are what make a creature grow. They come from transaction count and fees you paid, with a streak multiplier if you stay active across epochs.

Nothing is classified. A swap, a mint, a stake-pool registration - a transaction is a transaction.

Breadth vs Depth

Snacks are linear and uncapped, so a wallet with years of heavy history earns proportionally more. That is the reward for having actually been here.

What snacks cannot buy is depth. A creature gains at most two levels in any one epoch, however full the bowl is. Unused allowance does not roll over. Unused snacks do not expire.

Level 5 → 99 is therefore 94 levels / 47 epochs of perfect attendance - about eight months on mainnet - whatever you spend.

Stages

Genesis creatures and hatched eggs enter at level 5. Max is 99. The sprite also gets bigger at each stage - a hatchling is drawn small on the canvas; an elder fills it.

Stage	Levels	What you see
Hatchling	5–14	The adult body, eyes, horns, and markings, drawn small. The head is always a bud. No tail, wings, or gear. Beady and sleepy eyes stay wide so the face still reads.
Fledgling	15–29	Larger. The tail arrives: stub, spike, fluff, fin, or coil - or still none.
Adept	30–49	Wings (bat, plume, or fin) and gear (goggles, bandana, crown, lantern, lens, or antenna). Full eye set; some creatures start blinking.
Prime	50–74	Bigger still. Can lay an egg.
Elder	75–99	Full size. The level plate turns gold.

The look jumps at 15, 30, 50, and 75. The picture updates as soon as you feed across the line. A matching write to the on-chain datum is queued and rides along on a later transaction - you don't wait on it to see the new form. On-chain actions explains that queue.

The life path is fixed

Every trait is rolled from the seed at birth: the adult body, the adult horns, the colour, all of it. Growth only reveals that path. A creature never swaps one pair of horns for a different pair, and it never loses a feature it already had.

Tails wait until fledgling. Wings and gear wait until adept. Until then those slots stay empty. Body, horns, and markings are already the adult ones at level 5 - just small. The head stays a bud until fledgling. What you see at 99 was decided at 5.

An egg is a new seed derived from the parent, not a copy. Related creatures share lineage, not a silhouette, once they have grown.

Traits

A creature is a stack of parts, each picked once:

• Body - sleek, finned, bulk, spined, regal, or titan. From hatchling.
• Head - bud at hatchling. Adult head (round, long, angular, blunt, beaked, jawed, domed, or browed) from fledgling.
• Eyes - wide, beady, sleepy, sharp, or burning. Hatchlings and fledglings keep beady and sleepy as wide so the face still reads.
• Horns - none, nubs, ears, twin spikes, a crest, a spire, antlers, or a halo. From hatchling.
• Tail - from fledgling: none, stub, spike, fluff, fin, or coil.
• Wings - from adept: none, bat, plume, or fin.
• Accessory - from adept: none, goggles, bandana, crown, lantern, lens, or antenna. Gear, not anatomy; it keeps its own colours.

Over that:

• Palette - one of twelve colourways (ember, moss, tide, void, bone, coral, storm, gilded, verdigris, magma, frost, rot). Fixed for life.
• Backdrop - the scene behind the sprite (dusk, meadow, abyss, ash, aurora, sanctum). Not a stake-pool habitat.
• Markings - none, stripes, spots, a dorsal flash, or underlighting. From hatchling.

None of these are stats. They don't change how fast it grows, what it earns, or whether it can trade.

Personality

Each creature also has a personality and a one-line description, both from the seed. Flavour on the den card; in a crowded habitat it leans rumble odds without locking the winner. Eggs hide both until they hatch.

Personality has the ten types, the descriptions, and what they do when poked.

What wallets show

The image URL in the datum never changes. The content does, as the creature levels. Wallets cache hard; a new stage can take a few hours to show up in Eternl or a marketplace even though ouros.club already has it.
