Extra: Instead of listing the totals, it is best to look at the event thread itself as the amount of items and how they were distributed would make listing them more effort than its worth. Link
It is important to not that the Silver and Purple Pendants were given out as Free Items from a different NPC. It is also important to note that Day 6 had the chance to get a pet, which could potentially make the items from that day more common than the others.

luckydip- (4)
Extra:"Adoption limit was 4, but due to a glitch, some people got 6 or 8 coats. (Red coats were given out double for a certain period of time.) After the glitch was fixed, the limit was set back to 4."
What apparently happened is that if the person were to randomly get more than 1 red coat, it would double. Example: someone should have gotten 2 red, 1 black, 1 blue (4 outcomes), they would instead get double the red (4). This didn't happen if the person only pulled 1 red coat. This shouldn't affect item rarities as the bug was fixed 8 minutes after roll overDay 10
Extra:"Adoption limit was 3, but due to a glitch, some people got 4,5 or 6 coats. (Red/green hats were given out double for a certain period of time.) After the glitch was fixed, the limit was set back to 3."
The bug struck again, this time duplicating singles of the red and green. If someone had bad luck and got all 3 of their outcomes to be red/green, they would instead get 6. Fixed 5 minutes after roll over.Day 13
