1. Trelephant leaves. The trelephant is a colder-climate relation of the elephant. In order to conserve energy it spends the winter sleeping on one leg, similarly to the lawn flamingo. This, combined with the barkiness of their skin, leads to trelephants often being misidentified as trees. To add to the confusion, many trelephants are obsessive leaf collectors who like to display their collections along their many tentacles. They usually drop these leaves during their winter sleep. Trelephant leaves can be identified by their catalogue numbers, usually marked on the underside next to the stem.
2. Sock-worms. The small, translucent ghost-forms of these worms lurk in winter mud waiting for walkers to come past. When they spot a nearby boot, they float up through the sole and summon their own sock-worm egg back through time at the point of hatching, fulfilling their spiritual destiny and allowing the ghost to dissipate. The newly-hatched worm lives in the sock, eating little holes and dreaming about woodlands, until it is washed or squished. At this point it forms a ghost again and migrates back to the woods, ready for the next walker.
3. The bungalows of the Little People. You may need a magnifying glass to spot these, depending on how little your local Little People are. It is generally considered a sign of bad luck to have trespassed in the realms of the Little People to such an extent that you have tracked them home on your boots. The Little People cannot do a great deal to harm you, but they can definitely make you itch in places it is hard to reach.
4. Nether boots. Often dismissed as the result of standing on a reflective surface, the attachment of nether boots to the underside of your feet is actually a deeply worrying occurrence. You should detach them immediately with a sharp trowel. Otherwise you may find yourself slowly flowing down through your bootsoles into a nether copy who only exists in mirrored surfaces. Eventually, you may end up stuck as a reflection without a person in some frozen lake somewhere.
5. Hole seeds. These are small, purple and elongated, a little like grains of rice. They can often be found in boot mud following lengthy digressions from the proper path. If planted, they will grow holes of various sizes; some are large enough to enter and may even be accessorized with staircases or ladders. We are unsure whether this is a good idea or not. Nobody who has entered them has ever come back, but that may be because they have found an awesome reason to stay wherever they ended up.
