Dissection & Anatomy Lab — Surgeon-Sim Minigames for RPG Maker MZ

STEADY HANDS. REAL ANATOMY.

Surgeon Simulator meets biology class — inside your RPG Maker MZ game.

Dissection & Anatomy Lab is a drop-in plugin with 12 specimens and 7 hands-on minigames. Players pick their tools, trace incisions with a trembling hand, pin the specimen open, find the organs, lift them out without ripping anything, trace blood and food through the body, and file a lab report. Every structure comes with a real, fact-checked note, so players leave knowing more than when they walked in.

No image files. No coding. One .js file.

Part of the MZ Minigame Collection. This plugin is one of a growing library of themed minigames for RPG Maker MZ, from board games and puzzles to sports, casino and crafting. Mix and match to fill your world with things to do.

The 7 stages

1. Instrument Tray — Gloves, scalpel, scissors, forceps, probe, needle or pins? Pick the right tool for each real dissection task.
2. Incision — Trace each cut in the correct order and direction. Your hand trembles; Shift steadies it. Stray and you nick tissue. Hold still and you cut too deep.
3. Pinning — Pin the flaps to the wax tray with only two spare pins.
4. Organ ID — “Locate the LIVER.” Wrong clicks tell you what you actually touched.
5. Extraction — The Surgeon Simulator part. Snip the connective tissue, grab the organ with forceps and carry it to the dish. Rush it, bump a neighbour, or pull before you snip, and the damage meter climbs. (Never rush a squid’s ink sac.)
6. Physiology Pathway — Trace blood through a four-chambered heart, food through a gut, or water through a sea star, while decoy structures test what’s NOT on the route.
7. Lab Report — A short quiz on what you just saw.

Every run is graded A–F, with a pass/fail you set.

12 specimens, easy to hard

• ★ Earthworm — closed circulation and five “hearts”
• ★ Hard Clam — a filter feeder whose gut runs through its heart
• ★ Sea Star — hydraulic tube feet and a stomach that turns inside out
• ★★ Lubber Grasshopper — air tubes instead of lungs, open circulation
• ★★ Red Swamp Crayfish — a stomach with teeth and blood that turns blue
• ★★ Leopard Frog — the classic, with a three-chambered heart
• ★★ Longfin Squid — three hearts, a beak and a fragile ink sac
• ★★ Yellow Perch — single-loop circulation and a gas-filled swim bladder
• ★★★ Spiny Dogfish — a cartilage skeleton, a corkscrew gut and a salt gland
• ★★★ Rock Pigeon — crop, gizzard, air sacs and no gallbladder
• ★★★ Brown Rat — a giant fermenting cecum, and no gallbladder either
• ★★★ Fetal Pig — fetal circulation built around the umbilical cord

140 structures in all, each collected into an in-game Anatomy Atlas with a rendered plate and its fact.

Looks the part

Every organ is lit, glossy and shadowed, with its own tissue texture: spongy lung, lobed liver, fish scales, crayfish chitin, clam nacre, rat fur. The lab around it has a brushed-steel tray, a wax pad, a lamp glow, incision slits, droplets, shell chips, snip sparks and squid ink clouds. Stylized, never gory.

Built for developers

• One cabinet menu — Plugin Command → Open Menu lists every specimen, practice stages and the Atlas
• Start any specimen directly — full procedure or a single practice stage, with difficulty override
• Results into your events — score to a variable, grade letter to a variable, pass/fail to a switch; the event waits until the lab closes
• Easy / Normal / Hard, plus a tremor-off accessibility setting
• Add your own specimens with a documented data format, from a plugin below this one
• Script calls for start, menu, Atlas, records and last result
• Optional content advisory, once per save, for classroom and family-friendly games
• Toggle lamp lighting and particles for low-end devices

Setup

1. Copy Anatomy_DissectionLab.js into your project’s js/plugins folder.
2. Add it in the Plugin Manager and turn it ON.
3. Make an event: Plugin Command → Anatomy_DissectionLab → Open Menu (Lab Cabinet).

That’s it. Mouse, keyboard and touch all work.
