The Wicked Cat

It seemed like a normal cat -- at first. Adam and his friends are exploring the area around Spooksville when they come across a black cat. It seems like a friendly animal: it purrs when they rub its back, and licks its paws like any other cat.
But then if follows them back to town, and strange things begin to happen. A tree falls down, and a house catches fire. Each time something bad happens, the cat is there -- watching, with its strange green eyes. And it won't go away. Adam and his friends don't know what to do. Especially when the cat begins to use its powers on them.
