Let me introduce you ...
... to the weird, creepy and quirky oddlings, who live in a dark but nevertheless equally lovely place (true!) called "Odd between" or "Oddween". Its a very strange place between our world and the world of the dead. In the heart of Oddween next to the famous "Twistglade", where the worlds collide, lies the "Grumblevalley", a broad deep valley of strangeness where our rowdy rascal beings live. Sometimes - in rare (?) circumstances - they leave Grumblevalley through the Twistglade and visit the realms of the living or dead humans and create confusion and chaos. The little Oddlings are then often referred to by humans (dead, undead or alive) as "Strange little creatures".
Be careful if you come across them. They have been reported to eat brains and penisses on rare occasions. 😨
Notes
As a trigger phrase you can use "Strange little creatures", this should lead to good results.
