This challenge cache has a fairly-simple goal, but it could be difficult to qualify for it. We have taken the basic idea from a MA & PA KETTLE cache - GC1TK7G - along the Texas coast.
Here's your challenge: Find and log 26 caches, such that...
1) Each cache must have the name of an animal in it. This word can be generic ("cat" or "bird"), or more specific ("spotted owl" or "dire wolf").
2) Each of the twenty-six (26) animal names *MUST* start with a different letter of the English Alphabet. If you use compound names ("polar bear", say), then use the first letter of the entire name: in the case of polar bear, use 'P'.
3) The use of extinct animals (dodo, any dinosaur, etc) is allowed. The use of imaginary or fictional animals (dragon, heffalump or Magilla Gorilla) is also allowed. Just make sure that the name used refers to an animal. Feel free to ask us if you aren't sure about a name.
3a) We had not intended that "Yaardvark" be allowed. However, in looking over the rules, we realized that we changed one of them to allow for a couple of animals that we *did* want to count. Having done so, we cannot in good conscience disallow "Yaardvark", so it will count. FWIW, we actually found a reference to a children's book called "The Yaardvark", so our hands are tied 
4) Plurals count, as do possessives and adjectival forms: feline or canine, for example.
5) the animal name can stand alone, or be part of a longer word that obviously implies an animal. Examples of what will count: "Birdland", "Cat's-Cradle", "Elephantine Cache". What will *NOT* work are things like this: "Boondoggle" or "Foxen Canyon Cache".
6) Because very few animals start with the letter 'X', we will allow the use of any animal that has an 'x' in its name: e.g. "fox" or "Texasetes".
7) A cache with more than one qualifier (e.g. "Raining Cats and Dogs") can only be used once, for one of the qualifiers: your choice.
8) All cache sizes and types (icons) count. More brownie points for lots of icons 
9) There is no time limit: all Finds count, past, present and future, so you may already qualify.
10) You are free to sign the log, and post a Note, if you wish, even if you don't yet qualify. As soon as you have your 26 qualifiers, you can change the Note to a Found It.
You are looking for a camoed pill bottle hidden at something of which you'll see many around here. In fact, most of our AVCA hides are near/at one of these things. This one is in a hole, with some natural camo, but it isn't as low to the ground as our other ones are. There is safe, legal parking on the shoulder, a short distance from the cache. In rainy weather, it might be very muddy, so be wary. In winter, snow is "possible", although it rarely lasts for long if any does fall, but there might not be any way to park. And in summer it can get very hot 
When you claim your Smiley, post a list of the 26 (or more) qualifiers. See our Dropbox list for the suggested (but not required) format. When was approved, we didn't have an 'I', but we finally got one in December of 2012. You may do a public bookmark, or simply list the caches in your Find log. You may also attach a link to a list kept elsewhere: your personal server, a file-sharing site such as Dropbox, or any storage site in "the cloud".
Good luck! Have fun
