The Rubber Chicken with a pulley in the middle was an object that was first seen in The Secret of Monkey Island. However there have been references to this item throughout the rest of the series.
Guybrush Threepwood first imagined that the item would be completely useless, but in time found it to have several uses.
Secret of Monkey IslandEdit
It was used to slide along the cable connecting Melee to Hook Isle.
