What are the odds?

1 in 1728?

I bought my first one at the Main Street Emporium and got a Monkey Mickey. later I bought the next one at Star Trader and and got a Monkey Mickey. the next day I bought one at the Main Street Emporium and got a Monkey Mickey.

three Monkey Mickey's for my first three purchases. three different times on two different days.

later I bought an Urban Series 3 (just so I was guaranteed to get something different) and got a WDW Puzzle.

the next day, I decided to buy one more Park Series 2. I got Lion King Mickey. so the monkey chain has been broken.

Maybe they're just dumping a lot of Monkey Mickeys right now?

LOL That is kinda funny!
The good thing is that you have extras to trade for ones you want!

My very 1st purchase was a Green Tea Chaser somewhere in Animal Kingdom!
We also had about 3 or 4 Monkeys and 4 or 5 Confettis. Like NeverNeverLand said - You use them to trade for what you need or want!

I probably should have kept them for trading, but I gave two away.

there were three of us on this trip, so each of us got a Monkey Mickey.

From what I read before I believe Monkey is a case filler for series Park 2. Meaning there may have been 3 Monkey Mickey's in those cases of 24 boxes you chose from, 24 being 2 sets completed (11 make a set w/o chaser) so its set up like so 11x2=22 +1 chaser +1 filler= 24

A small list of known fillers below (depending on the case)

Park 1- Monorail Red
Park 2- Monkey
Park 3- America Sings

Urban 1- Oopsy!
Urban 2- Girlie
Urban 3- Orange Gears

Muppets- Miss Piggy or Rizzo.
Holiday 1- American Flag, Melty the Snowman or Ghost
Clear- Dark Blue
Cutesters- Ladybug

I've only bought 7 3" vinyls thus far and already got 2 vinyls listed from fillers above so wouldn't be surprised if I get any dupes of them eventually. But 3 of 3 pulls, wow.
