I've just been examining the bump codes for the new series 11 figures for the past few hours, and there is a bump conde that The Lego Group uses as a red herring, and I noticed that it could be many things.  Use yr feeling sense if you get this code:

The code has 4 dots, 2 on the left half of the bump code area and two on the right.  All 4 dots are relief, none incused.

Examine the 2 on the left side of the middle strip.  1 bump is 1/5 between the left edge and the center strip, the other 3/5 the way between the left edge and center strip.  The one on the right is slightly lower than the one on the left.  Both bumps are well south of the "equator" of the bump code area.

Examine the 2 bumps on the right side.   1 is just over 1/3 the distance from the center strip to the right edge, the other 2/3 the way from the center strip to the right edge.  Again, the left is higher than the right bump, but this time ithe difference is a little more prominent.  The left bump is jsut "south" of the "equator" of the bump code area.

Also notice that besides red herring, there are at least THREE bump codes for the Yeti.  Feel for the space where the beard fits into the minifigure torso, and find that smooth ice lolly piece.  It's easy to shake & find, and feel for the "stick" on the end of it to be sure.

In the 100+ statistical sample I examined so far (I'll be checkinf 360 in all), the Keystone Kop is cuper common, as is the bug spray guy and red rescue man.
