Final Product: Travel Milk Frog (旅行奶蛙)
Cover
The page key art, generated 16:9 with GPT Image 2 in the world’s own palette: the canonical butter-yellow milk frog in a felt hat and travel satchel stands on the pixel-meadow path beside its red-roofed cabin, while framed museum postcards — a milk-frog Mona Lisa, Sunflowers, the Great Wave and Girl with a Pearl Earring — float around it on an aged cream museum-poster ground with thin gold hairlines.

The real game, opening view. The travel corner renders a 320×180 pixel cabin scene — red roof, picket fence, hollyhocks and a sandy path — with a live stat bar (money grass, 0/94 collected, letters, trips) and the five tabs 旅行角 · 信箱 · 明信片墙 · 图鉴 · 记录. The caption under the meadow reads “点草地上的钱草收一收 · 按住扫过收更多” — tap the money grass, or press and sweep to harvest more.

What one trip actually returns. After choosing an interest item, a supply and a trip length, the frog walks out and comes back with two catalogued works (a milk-frog reworking of Kuniyoshi’s skeleton figure and of the Altamira cave bison), a handwritten letter, a travel photo and a running log entry — every card linking straight back to the museum original.
Travel Milk Frog (旅行奶蛙) is a free browser pixel-cabin game generated by Neta Studio inside the milk-frog museum world. You keep a sunny low-resolution cabin, harvest money grass from the meadow, then pack the milk-frog mascot a bag: one interest item that steers which eras it gravitates to, one single-use supply, and a trip length. Send it out and wait — while it is away it walks real galleries and comes home with a milk-frog reworking of a famous painting, a letter and a few travel photographs, all filed into an album that fills toward 94 works across 16 galleries.
It is one static pixel-art web app: no install, no account, no ads and no purchases. Everything is drawn at the game’s native 320×180 pixel resolution and integer-scaled, so the whole thing loads in about a second on any device. The frog’s collection overlaps the other milk-frog sets — the museum, the card pack and the stamp album — but the framing, the route and the rarities are its own.
Features
- Collect 94 Real Masterpieces — The catalogue holds 94 milk-frog reworkings of real paintings, spanning 16 galleries from prehistory and Qin–Han China through the Renaissance, Romanticism, Ukiyo-e, Impressionism and Modernism. Every collected card names the original work and artist and links straight to the museum entry — so the collection you build is a real art-history syllabus, not filler.
- Pack a Trip in Three Choices — Each journey is three picks: one of five interest items (a folding map, an oil brush, a ukiyo-e block, a telescope or a small camera) that decides which eras you are most likely to meet, one of five single-use supplies (rice ball, dried fish, picnic box, milk tablet or blank postcard) and one of four trip lengths. The combinations change both the loot and the story you get back.
- Money Grass, Not Microtransactions — The only currency is money grass growing in front of the cabin: tap a clump to collect it, or press and sweep across the meadow to gather far more at once. It pays for interest items, supplies and longer trips. There are no ads, no in-app purchases and no energy timers to pay away.
- Letters, Postcards and a Live Log — Trips do not just produce art. The 信箱 fills with first-person letters written in the frog’s voice, the 明信片墙 collects the travel photographs it takes, and the 图鉴 and 记录 tabs keep the full album and a running written log of every outing — so the world accumulates a diary as well as a collection.
- Time Really Passes — A first stroll is free and takes 30 minutes; a short walk is 2 hours, a long expedition half a day and a half-day ramble a full day. Trips run on real clocks and longer trips return more works, rarer ones — and the half-day ramble only unlocks once you have catalogued 12 pieces.
- A Crisp 320×180 Pixel Cabin — The whole scene is baked and animated at the game’s native 320×180 pixel buffer and integer-scaled up, so the sky gradient, drifting clouds, hill layers, fence, hollyhocks and the frog’s walk cycle stay sharp on any screen. It runs in the browser with no install, no signup and no permissions.
Interface
UI
The travel corner (旅行角) is the game’s home: the live pixel scene sits above a stat bar tracking money grass, collection progress (0 of 94), unread letters and trips taken, with the five tabs 旅行角 · 信箱 · 明信片墙 · 图鉴 · 记录 underneath and the harvest hint pinned to the meadow’s edge.
UI
The trip planner is three numbered steps in one column: ① 挑一件兴趣物 (choose an interest item) with the five options and their money-grass prices, ② 塞一份补给 (pack one supply) highlighted once selected, and ③ 选好时长 (choose a duration) with the first stroll free and the half-day ramble locked. The live cost and your balance sit right below the last row.
UI
The return screen is the payoff: “回来了 · 带回了 2 件馆藏” heads a modal that stacks the collected masterpiece cards (each tagged 珍品 / 杰作 and linking to the museum), the letter the frog wrote home, the labelled travel photo and the running log, with a 收下，继续 button to file everything away.
Production Process Breakdown
Stage 1: World and Character Designclaude-opus-5
The world begins from a single line — “I want to build a milk-frog museum site that exhibits world-famous paintings and artworks reworked with milk frogs; the UI and layout should reference breguet.com, very high-end.” From that, the canon is locked: one official Milk Frog character atom fixes the pear-shaped body that flows into the torso with no neck, the large pale-cream belly, exactly two pale-green eye rings each holding a flat black pupil at 45% of the ring’s diameter, one tiny straight mouth line and short taupe mitten hands. Travel Milk Frog keeps that identity untouched and re-frames it as a cosy pixel-cabin collecting loop instead of a museum page.

Stage 2: Asset Direction and Generationgpt-image-2birefnet-general
Art direction is fixed before anything is drawn: warm museum-poster cream, thin gold hairlines, flat matte colour and generous negative space. The 94 painting adaptations and the official Milk Frog reference sheets are generated with GPT Image 2, the 16:9 key-art cover is generated at 2048×1152 from the same identity lock, and the character art is cut to transparent PNG sprites with BiRefNet and rembg. The game scene itself is drawn in code at a 320×180 pixel buffer so it stays crisp when integer-scaled.

Stage 3: Build, QA and Publishdeepseek-v4-flash
The game ships as a small static web app — one HTML document, one stylesheet and a handful of scripts driving a canvas pixel engine with per-element animation phases — so it loads instantly and needs no backend. QA opens it in a real browser, sweeps the money-grass meadow, runs every interest item, supply and trip length through a full loop, checks that each collected card links to the right museum original, and then publishes the finished work to a shareable browser URL.

Mona Lisa as a Milk-Frog Oil Painting Promptgpt-image-2
Reimagine Leonardo da Vinci's Mona Lisa as an oil painting, but the sitter is the round butter-yellow milk-frog character from the reference (soft plump body, cream-colored belly, calm green eyes, gentle closed-mouth smile). The frog sits in the exact three-quarter Mona Lisa pose, hands folded, before the hazy Renaissance mountain landscape with winding river. Sfumato technique, cracked aged varnish, dark museum-oil palette, golden-brown tones. Faithful to the original composition and lighting. No text.

Vermeer’s The Milkmaid as a Milk-Frog Painting Promptgpt-image-2
Reimagine Vermeer's The Milkmaid. A sturdy milk-frog in a linen cap, yellow apron and blue skirt stands at a table pouring a thin stream of milk from an earthenware jug into a bowl, cream belly rounded, calm eyes down at its work. Soft daylight from a left window, bread and crockery on the table, plaster wall, quiet Dutch domestic oil realism. CRITICAL RENDERING RULE: Use the stylized simple cartoon milk-frog from the reference image — smooth matte butter-yellow rounded body, large cream/ivory belly, simple round eyes, tiny calm mouth, stubby grey-tipped limbs. NOT a realistic textured frog. NOT a frog head grafted onto a human body. The plump frog IS the entire figure, repainted completely in the target masterpiece style so it dissolves into the original brushwork, texture and palette. No text, no signature, no watermark, no border captions.
