Do you remember your first vanity pet?

Do you remember which of your many vanity pets was the very first you got? I was trying to figure that out today and I realized that I couldn't recall it.
Unfortunately I expect that not even Blizzard can track the exact truth, since creation dates probably got wiped when the pet journal was introduced, but I thought that perhaps looking at the list would jug my memory, so I opened the pet journal to give it a go.

First I unticked all pet gained through pet battling. Having played since 2005 I was certain that my first pet would not be amongst those. I also unticked Blizzard store pets and pets gained from the trading card game as I didn't start getting pets from those until the summer of 2008.

This left me with quite a long list still. Scanning through it I narrowed it down to 3 pets.

The mechanical chicken is the one I think is most likely.
You get it from the quest An OOX of Your Own which opens up after you have done the escort quest for 3 mechanical chickens in 3 different zones. 
I am pretty sure I did this on my very first character, which means I should have gotten this pet at some point during 2005. 

The question is whether I completed the quest chain before or after May 2005 because if it was after, that leaves room for my guess number 2.

Speedy is one out of 4 different pets you can get from the original Children's week quest line. 
The other choices are Mr. Wiggles, Scooter the Snail and Whiskers. I am 100% certain that I chose Speedy as my number one, I vividly remember having a hard time picking between him and Mr. Wiggles and ending up with him as my choice. I don't remember if this happened in 2005 or if it wasn't until 2006 that I realized this quest line was available. Looking through the list though I have discovered that I am still to pick up Whiskers and that I have 2 Speedy's which is a bit silly, but at least I know which reward to pick next year! 

The Winter Reindeer along with the Tiny Snowman and Father Winter's Helper is another good guess. The pets were introduced to Winter Veil in 2005 and you could get them from opening the presents under the tree. 
I know that I have done this every year since the beginning so the question is just whether or not I received one of the 2 above pets before getting either of these 3 Winter Veil ones. 
Sadly I can't remember, but all of these 3 pets required a snowball to summon back before they were put into the pet journal, so even if one of them were my first pet, it hasn't seen much use as snowballs were rare except for during the holiday. 

Given that my first character was an Undead, it would actually have made a lot of sense if my first vanity pet had been the Undercity Cockroach. But it wasn't. In fact I didn't get any cockroach until I wanted to test out the Apocalypse ability when fighting Dos-Ryga. 
Why you ask? Well I think they are ugly and disgusting, even in pixel form, but the main reason back in the early days of WoW was that even 50 silver was quite a big deal. Remember this was back when a slow mount cost 40G and the fast one 600G. Not many people could afford the latter, but I got mine the moment I turned 60. One of the reasons I could afford that was because I didn't spend money on anything that wasn't absolutely necessary and that is how I know for a fact that my first vanity pet must have been from a quest or an event.
So this is my guesses for my first vanity pet. Do you remember which one was your first?
