need a sesame street reference

[Sesamo2012]

Does any one that has been watching sesame street remember seeing the sesame street segments of this shadow that was made once in few segments. does any one have any idea were i can find these segments to watch of do reasearch on for this class that is being taught this fall, the reason being is we are looking for some that were not recovered from sesame street and some that were redone are not the same as they used to be. so if any body can shed some light on this i would be gladly able to thank those for helping.

also does any body want a copy of sesame street episode 2282, and 3167 one is from sesame street 2282, and the other is from noggin and sesame street unpaved, if any one would like that, also does any body have a copy of 2556 or 2874 if any one has it thanks
