A cape texture is 2,048 pixels and only 372 of them are ever drawn

The file is 64×32, the cape lives in a 22×17 corner, and the side people actually see is 160 pixels — under 8% of the image. Plus the one-pixel offset that catches everyone.

A trimmed armour set has 1.57 billion possible appearances, which is why the lock button exists

199 states per slot to the fourth power. Rerolling all four at once will never converge on a look — locking the pieces you like turns an unsearchable space into a workable one.

A Bedrock skin pack is four files, and two of its failure modes are silent

Two UUIDs that must differ, a lang file that is not optional, and skin keys that strip punctuation — so 'My Skin!' and 'My Skin?' become one skin with no error.

Bedrock has no standalone cape pack — a cape only ships attached to a skin

There is no cape-only .mcpack format. Every cape must be paired with a skin entry that names it, which is why a cape pack is really a skin pack with an extra PNG per entry.

Biome temperature decides rain, snow or nothing — and 18 biomes get no weather at all

66 biomes in 26.2. Every biome at temperature 2.0 is dry, all six remaining dry ones are in the End, and only 10 biomes actually snow.

Breeding food: 17 of the 31 mobs accept exactly one item, and bees accept 29

Minecraft defines breeding food as tags. Over half the mobs take a single item, horses and wolves take eight, and the frog has a food tag pointing at other mobs.

Alternating rows grow twice as fast as a solid field — the formula says so

Moist alternating rows give a 1-in-3 growth roll; a dry solid field gives 1-in-13. Planting every block halves your growth points, and hydration is worth more than layout.

Custom paintings and discs need two packs, and installing one of them is the usual failure

The datapack registers the content; the resource pack supplies the texture and the sound. Datapack alone and it registers with nothing to show. Plus the 4×4 limit and why disc length is not cosmetic.

Eighteen trim patterns, fourteen places, and only one that drops from a mob

Trail Ruins gives four of the eighteen. Tide is the only pattern that is not loot. And duplicating a template is a crafting table, not a smithing one — with two exceptions.

Fourteen items have exactly one way in, and three have a way that exists only for them

Nether Star is the only Boss Drop, Dragon Egg the only One-Time item, Command Block the only unobtainable one. Plus the fourteen things no chest, craft or trade will ever give you.
