Random Magic

Random magic is magic randomly occurring in random objects and locations in the series.

Random magic happen usually in the form of Transformation Spells, Teleportation Spells, and undisclosed portals. They can be discovered by any species of being or beast and happen often.

Portals
Undisclosed portals are portals that were left untended to and went on using the Portal Potion for way too long. They are mostly movies, video games, or books that have been splashed with an overdose of Portal Potion and was never used and abandoned by the user. Here are some examples:

A person named Billy Brooks once fell into a copy of the Half-Blood Prince and explored Hogwarts for several months until he was able to find a copy of fairytales belonging to a Hufflepuff third-year girl and was able to be freed. The copy’s portal was broken by him and he was able to keep the copy.

Once, a donkey had fallen into a copy of Minecraft and came back with a burnt carcass (presumably it found a Nether portal and was able to cheat but returned burnt and dead)

There are rumors of a girl who ate a salad went on an adventure in Insurgent while sitting on her dinner chair. It has been unproven.

A copy of the Goblet of Fire once had a blue light glowing over it and it came out with 20 Blast-Ended Skrewts, who ruined the room of the boy who owned the room.

Northernian Fred Williams was imprisoned in an asylum because he said he once entered his copy of Mockingjay to go save Finnick.

Silas Evergreen, a man from Chariot Hills, was said to have an unusual death by falling into shadows (presumably a Lethifold), featured in Unusual Deaths. As there have been spells to stop creatures from Wizarding World invented by fairies, Silas either had weak magic (like the Sisters Grimm and the Charming family) after being passed down for centuries, or was unrelated to Brystal’s family. The Lethifold’s fate, however, was unknown, even though it was mentioned to be taken care of by local law enforcement.

Transformation Spells
These are more covered in classic fairy-tales, notably by the Grimms.

In Fundevogel, Foundling and Lina each had six forms while the pair hid in the woods.

In the Pink, The maiden was turned into a lilac and a cook turned into a dog to chase the maiden and a prince.
