Very wisely, you read the letter before messing around with the other stuff.
"Dear Sir,
You have been selected as compatable for our experimental K9 project. With this letter you will recieve a special collar. upon wearing this collar, you will be able to transform into both a werewolf (an athromorphic wolf with super strength) at night and a large dog by day (although unable to speak in dog form). You will also find a police dog uniform tailored to fit, some dog food and other nessecary tems to help you mantain your canine form.
If you do agree to join our unit, apply to your local station in whatever form you like. If not, you are strictly required to return all items to said station where your memory will be wiped of this secret project.
We look forward to your reply."
