Letters in Chains / Hints

I think Pandora may have posted this puzzle some years ago. It has a Halloween flair.

Find the members of a hidden category by linking letters. Each letter on both sides of the arrows is used at least once. Most answers are single words, but some may be hyphenated or multiple word answers. As you solve, you may find words that don't fit the category - these should be discarded.

Start with a letter on the left of an arrow and link it to one of the letters to the right of the same arrow. Find that second letter on the left and link it to a letter on its right. Continue the process until an answer is formed.

The number in parentheses indicates the number of answers in the category. Each answer is at least five letters long. Please answer an entire category.
