The Legend of Grandma
At a Christian day camp in Ohio, two friends, both around 19 years old, were working as short-term staff. They were familiar with the camp and its counselors. One day, they asked a few of the counselors if they knew about any local cryptids. The counselors were more than willing to tell them about a creature known as "Grandma."
Described as a small, goblin-like being, Grandma was said to reside on the far side of the field, beyond the trees. Older kids usually avoided it because they knew what could happen. The younger kids, however, either hadn’t heard of Grandma or didn’t believe in it, and would go looking for it.
If the kids ever managed to find Grandma, they would chase it. When Grandma felt too threatened or backed into a corner, it would viciously attack the children. This left them with scratches, bruises, and in one case, a child even ended up with a broken arm.
