Little Monsters is Beetlejuice's sillier little brother. It doesn't revolve around the afterlife but rather the secret world where all of the monsters who live under children's beds live. After a young boy named Ben befriends the monster under his bed, he's whisked away to his monstrous new pal's strange world every night. And while it's fun at first, he quickly realises not all of the monsters are as welcoming as his friend.
