Crocodile - Dungeons on Automatic Bestiary

Animal · 3 hexes · SM +2 Crocodile [Monsters on Automatic, SRD coverage: mundane birds, fish and aquatic animals; answers Crocodile (SRD 5.1); Crocodile (SRD 3.5)]

Four metres of armoured patience lying as a log until the moment it is not. It takes prey at the water's edge, drags it in, and drowns it, and its hide turns a spear that would go through anything else this side of a dragon. Out of the water it is slow. In the water nothing is winning.

Notes

GCS ancestry draft: gcs/crocodile.gct
Independent build total: -28 points of racial traits plus 18 points of racial skills.
Answers the SRD heading(s): Crocodile (SRD 5.1); Crocodile (SRD 3.5). Only the creature identity is taken from the SRD; the GURPS statistics, ratings and prose are this project's own work and reproduce no SRD text.
Typical Stats, damage and ratings are derived from the racial template, not authored beside it, so the sheet and the stat block cannot disagree.
Body mass used to scale this build: 350 kg. ST, Size Modifier and DR are checked against it; see the gurps-animal-sanity-check skill for the bands.
Movement: ground Move 5; water Move 5, 7 at a sprint (primary). The published Move is the primary medium's cruising Move; sprint figures are stated here and not folded into it.
Treasure and grappling are not authored for this batch and ship as explicit nulls; `lair` carries a short habitat note, because where a wandering animal dens is an encounter fact rather than a loot one.
Four metres nose to tail puts it on the SM +2 row. Length, not mass, is what the published table reads.
ST from Basic Lift: it drags an 80 kg carcass into the water, which is the job its strength has to do.
DR is full armour rather than Tough Skin: osteoderms are bone plates, not thick hide.
Added after a post-hoc comparison against independent GURPS fan conversions of this creature: Peripheral Vision; Rapid Healing; Resistant To Disease; the Tracking skill, which a creature with Discriminatory Smell should always have. The comparison surfaced the gap; the build is still ours.

Independently authored GURPS build. The SRD supplies the creature identity this record answers to and nothing else: no SRD statistics, wording or presentation is reproduced, and no third-party GURPS conversion was used as an input.
Answers the SRD heading(s): Crocodile (SRD 5.1); Crocodile (SRD 3.5).
Racial template: -28 points across 22 traits, plus 4 racial skill(s) worth 18 points.
Every trait is drawn from the project's controlled GURPS vocabulary in scripts/srd/trait-library.mjs, which carries the page reference and published cost for each entry.
sourceSystem is recorded as doa_fixture because that is the package contract's value for project-authored material; the SRD headings this record answers are in provenance.coversSourceIdentities.
Ratings are recomputed through the consumer CER path on every build, so a mechanics change cannot leave a stale rating behind.
