This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Tikoloshe (Zulu)
In Nguni mythology, Tikoloshe, Tikolosh, Tokoloshe, Tokolotshe, Thokolosi, or Hili is a dwarf-like water spirit. It is a mischievous and evil spirit that can become invisible by drinking water or swallowing a stone. Tokoloshes are called upon by malevolent people to cause trouble for others.
At its least harmful, a tokoloshe can be used to scare children, but its power extends to causing illness or even the death of the victim. A dwarf-like water sprite thought to be extremely mischievous and troublesome. The tokoloshe is committed to causing problems for humans and can turn invisible and escape capture, but only if it drinks water or swallows a stone.
