Secret detail on the Angel doll!

Photo is of the back of the Angel doll from the Buffy and Angel two pack. There's a tattoo depicting a stylised winged lion above the letter A on his right shoulder blade

I stripped his top off to try other clothes I have on him and found that they gave him the tattoo!!! What a fun detail from the show to include, especially considering how many people never take the Skullectors out of their boxes and may never know about it!

What other dolls have secret details people might not know about? And I don't mean the images in their eyes that you'd see in the promo photos- I mean like the cobwebs in g3 Twyla's ears and the tattoo above that wasn't advertised.
