3m. From a sitstart take the lip from right to left, then mantle. This is noted within the Jingo Wobbly Fun Bloc page149 and is just down from "Hareng" boulder.

Not entirely sure I took the right route at the top-out, the Jingo Wobbly book suggests around the lip of the top of the rock whereas other climbers seem to top out before that... Anyway I did the what looked right!
