[Closed] Advent Calendars, potential for improvement?

Advent Calendars, associated in my mind with 25 (or 24 if it was a cheapskate calendar) very small mis-shapen chocolates of dubious taste, although I do remember Singletrack doing an advent calendar prize a few years back and giving away a selection of bike related goodies, albeit not to me.

I had somehow missed that things had moved on until last year when my son put in an order for a toolkit advent calendar and this year my daughter has gone for a fashion and cosmetics version, which got me thinking as to what consisted of 25 or so parts that I could get into the house on the basis that "It's just an advent calendar."

So

1) spokes

2) hubs

3) pedals

4) rims

5) tyres

6) saddle

7) seatpost

8) shifter(s)

9) rear mech

10) bars

11) stem

12) grips

13) rear brake caliper

14) front brake caliper

15) brake hoses/cables

16) bottom bracket

17) gear cable(s)

18) crankset

20) cassette

21) chain

22) brake levers

23) front mech

24) brake rotors

25) frame

Now can I get it all in box I can fit under the tree, and still fit the tree in the front room?
