We all know about the Masquerade achievements under the Seasonal tab, however there are several other achievements that you can earn from items purchased from the Libertine Lounge and Steamworks Menagerie under the regular achievement tabs - books, wardrobe, food, etc. I've listed all those other achievements here.

To make it easier to find these items within the shop, I recommend adding [userID=661952] CSS code from the CustomCSS: Year Indicator for yearly event shops.
Please let me know if I've overlooked any achievements/items. I've focused on achievements which are not found under the seasonal Masquerade tab and with items that can be purchased from the Libertine Lounge and Steamworks Menagerie.

For the feeding achievements you need to feed all the items from a single achievement to a single pet. However, you can feed all the items from, for example "Who run the world" to one pet and "Shake that healthy butt" to a different pet. Most of the time it won't matter. In this case, however, there are a number of food items that show up in two different achievements, so you might want to make sure you feed the same pet both sets of those items so you only need to purchase one.
