Zuberi

Zuberi was born in Alachyme in the year 1456. His parents were Mr and Mrs Yoholo, and they were very poor at the time. throughout his childhood he enjoyed walking around the farm his parents owned and picking up random creatures. His favorite creatures were toads because they tasted like gushers inside his mouth. He didn't interact with humans often though because his family was outcasted from the village.
One day while carrying around a potato sack he encountered a traveler from the far land of Ethiopia. the traveler gave him a tempting offer. He said "If you give me all your potatos, i'll give you all the toads in the world." Of course, the young and naive Zuberi fell for the obvious trap. Without thinking he gave his potato sack to the traveler and the traveler ran as far away as possible. Zuberi, feeling rage and grief, felt so angry that his head popped off and started floating searching for the traveler.
The traveler was so far away from Zuberi that he was not able to catch up to him. He searched all over Europe but didn't realize that humans have a shorter life span than him, so to this day he still searches for the traveler, devouring every toad and human that comes in his way. Whenever you're out in the lake with toads and hear a loud scream, be wary of Zuberi.
