Harry Potter Magical Creature Picker
What climbs out of the case?
Creatures in the case
Tap a creature to keep it in the case — all 16 fit at once, and you can add your own.
Pick which magical creatures are in the case, then rattle it. It shakes harder and harder until the lid bursts open — and one beast climbs out, with a line on exactly what you have just let loose.

A random magical creature, straight out of the case
The Harry Potter Creature Picker chooses one of sixteen magical creatures at random — but instead of spinning a wheel at a list, you let one out of a case. Rattle the lid, watch the case shake harder and harder while shapes jostle behind the slats, and see what climbs out when it finally bursts open. Sometimes it is a niffler. Sometimes it is an acromantula, and you should have run.
How it works
Choose the creatures
Tap the beasts you want in the case. All sixteen fit at once, or narrow it to the shortlist your scene actually needs.
Rattle the case
The case judders and strains, harder and harder, with a blur of creatures flashing behind the gaps in the slats.
The lid bursts
The rattling peaks and the lid flies open on its hinge in a spray of light and dust.
See what you got
One creature rises out and a hanging tag drops in below with its name — and a line on what you have let loose.
The sixteen creatures, and what you just let out
A name on its own is not much of an encounter — "you got a thestral" lands differently once you know it is a skeletal winged horse that only the bereaved can see. Every result here comes with a line on the beast, and the object that stands in for it on the case.
| Creature | Class | On the case | In one line |
|---|---|---|---|
| Dragon | Beast (XXXXX) | Horned head + wing | Armoured, fire-breathing, and near-impossible to keep. Ten breeds, none safe. |
| Phoenix | Beast (XXXX) | A rising firebird | Bursts into flame and is reborn from the ash. Loyal, and carries huge loads. |
| Hippogriff | Beast (XXX) | Eagle head + haunch | Eagle in front, horse behind, fiercely proud. Bow first, and it may let you ride. |
| Basilisk | Beast (XXXXX) | A crested serpent | King of serpents. A direct look kills; even its reflection petrifies. |
| Thestral | Beast (XXXX) | Skeletal winged horse | Gentle in the dark, visible only to those who have watched someone die. |
| Unicorn | Beast (XXXX) | Horned horse head | Pure, impossibly fast, and its blood keeps you alive at a terrible price. |
| Niffler | Beast (XXX) | Snout + a gold coin | A soft digger with a bottomless pouch and a helpless love of anything shiny. |
| Bowtruckle | Beast (XX) | A twig-limbed figure | A tiny tree guardian. It will pick a lock for a friend and jab an eye for an enemy. |
| Dementor | Non-classifiable | A hooded wraith | Feeds on happiness and leaves you your worst memories. Only a Patronus repels it. |
| Boggart | Non-classifiable | Eyes in a wardrobe | Becomes whatever frightens you most. Its true form is unknown. Laugh at it. |
| Acromantula | Beast (XXXXX) | An eight-legged spider | A house-sized spider with a taste for flesh and a colony behind it. Run. |
| Merperson | Being | A tail + trident | Dwells in cold water; its song screeches above the surface and enchants below it. |
| Giant | Being | A club-bearing figure | Twenty feet of bad temper and blunt force, nearly extinct and easily provoked. |
| Centaur | Being (self-styled beast) | A horse-body archer | Half human, half horse, and wholly done with wizards. A brilliant astronomer. |
| Werewolf | Being / Beast | A howling head + moon | An ordinary person most days; a lethal, mindless wolf under the full moon. |
| House Elf | Being | Big ears + tunic | Small, powerful and fiercely devoted — until someone hands it clothes, and it is free. |
Why a case, and not a wheel
A picker for creatures had an obvious wrong answer: a spinning wheel with sixteen names on it. It would work, and it would waste the best thing a creature has, which is the not-knowing. The whole appeal of a magical beast is the moment before you see it — the case straining, the lid banging, the shapes moving behind the slats — and then the thing itself, climbing out.
So that is the mechanic. The rattle building to a burst is the pick, and it is an encounter rather than a dial coming to rest. It also keeps the page off the one shape a site built on not-being-a-wheel most needs to avoid: a pointer going round a ring.
The ones you don't want to draw
Half of this case is a creature you would be delighted to meet and half is one you would sprint away from. A niffler is a soft-bellied thief; an acromantula is a spider the size of a car with a colony behind it. A unicorn is the most protected creature in the wizarding world; a dementor is the least welcome thing in it. A phoenix will carry you to safety; a basilisk will kill you if you so much as glance at it.
That split is exactly what makes the draw worth doing. A case of nothing but friendly beasts has no stakes; the chance that the lid bursts open on something with too many legs and teeth is the whole reason to rattle it.
A shortlist beats the whole case. Sixteen creatures means each one comes up about one run in sixteen. If you are drawing a creature for a scene you will actually write, put in only the four or five that would genuinely change what happens next.
Beasts, beings and spirits
The wizarding world sorts its creatures into rough classes, and the case deliberately holds a spread of them. The beasts are the animals — the dragon, the hippogriff, the niffler, the acromantula — graded from a harmless XX up to the XXXXX reserved for the ones no wizard should keep. The beings are the creatures with enough intelligence and voice to sit at a table and be reasoned with, or refuse to be: the merperson, the giant, the house elf, and the centaur, who is bright enough to qualify as a being and proud enough to reject the label.
Then there are the ones that fit nowhere. A dementor is not really alive, and a boggart has no fixed form to classify, which is why the case treats them as their own category — the spirits and the shapeshifters that the tidy grading system quietly gives up on.
Ways people use it
Writing a scene
Draw a creature and drop it into the next chapter. The beast does half the work — a chapter with a niffler in it is a different chapter from one with an acromantula.
Tabletop and fan RPGs
Roll for what is in the crate, what the party finds in the forest, or what the lesson is studying this week. The dangerous draws make the best sessions.
Quiz and trivia rounds
Draw a creature and ask the table what class it is, how you handle it, or what repels it. The obscure beasts make far better questions than the dragon does.
Which-beast-are-you
Let the case decide your magical creature for a bio, a profile, or an argument. It is more fun when it hands you a boggart than when you pick a phoenix.
Why the artwork is silhouettes
Every drawing here is original, which rules out a faithful depiction of any of these creatures — those designs belong to their illustrators and studios. Each beast is a plain silhouette instead, drawn in the same wizarding ink style as the rest of the Harry Potter set: a dragon's horned head and spread wing, a spider's eight splayed legs, a hooded wraith with a reaching hand, a small figure with enormous ears.
The silhouettes also have a job. A creature flashes past fast behind the slats during the rattle, so the emblem has to read as an outline, not a portrait — a shape you recognise before you have finished looking. It is the same constraint the character picker and the location picker work under, which is why the wizarding pages look like one set.
A fair pick, every time
The creature is chosen by your browser's cryptographic random generator before the case moves, and the rattle is then built to burst open on that one. It uses rejection sampling, which removes even the tiny bias a plain remainder would leave, so every creature in the case has exactly equal odds — and the glimpse order behind the slats is reshuffled on every run, so nothing about the animation favours one beast. The encounter is theatre; the decision was already made fairly.
