Masquerade

You're after the crime boss, Mr. Topp, but so far you've had little luck. Your only lead is an unconscious stooge in a cheap hotel. Fortunately, he has a few things on him that give your investigation a boost. You'll be led in short order to the local zoo, where you'll meet up with a useful snake, a bird that can be very friendly, a gorilla that just can't, a pack rat, and a couple of zoo employees. - The Book of Adventure Games II
