She is covered from head to toe in an old thin black cloak, her hands and feet are gnarled bird legs, her face is yellow and consumed by rough and hairy warts, her eyes are tiny and bright as stars.
Her aquiline nose and mouth contain a single black razor sharp tooth that which extends long enough to be under her chin and used to suck blood.
Guajona invades homes without getting noticed and walks silently toward healthy young children to suck their blood in their sleep by sticking her tooth into their veins.
She does not kill them, instead leaving them almost bloodless so when they wake up in the morning they will be tired, pale and discolored.
The origin of Guaja or Guaxa could be in classical Arabic وحش wahsh, meaning "beast".
