Best friends, Oscar (an elephant) and Hedgehog (uh...a hedgehog) are spending summer at a summer camp on an island, but once they arrive, strange things begin to happen. Their camp counselors are witches. Seemingly inanimate objects like pajamas, trees, food, and even the Moon, come to life and talk, and there are monsters, aliens, ghosts and many other strange things around. It is not going to be an ordinary summer.
