In the sector Tom & Jerry. Sitstart under the overhang, low traverse, pass the angle and exit via a mantle at the top of the boulder. Access: from the Obélisque of Fontainebleau, take the N152 for 4km500 in direction of Ury and park along the road 300m before Le Carrefour de la Croix de Souvray (crossing with La Route Ronde de Franchard). Follow La Route des Petites Maisons for about 150m from the N152, turn right at the thalweg, pass Pirouette Cacaouette and Cap ou pas Cap: the boulder is 100m further, in the Western face. Update (March 2017): a hold has stupidly been enlarged at the start on the arete which makes the problem a little easier. The original version exits a little more to the left than shown in the videos or the repeaters.
