Fully of Martindale: and the Adventures of the Cousins in Bloomington, MN

Their parents would take a while to return and their grandmother slept as did the youngest and oldest of the cousins.
They had an entire afternoon to play without bothering or be bothered and they decided to make a giant nest with tree branches. Everything changed when Natalia was looking for a place to store the collected branches and heard "Psst psst!" The noise came from Fully of Martindale, a very unique monster. Soon she was joined by the others and along with Fully's powers, they gave Abu, their grandmother, the strangest nap she could have ever imagined.
