For the d/b+2 attack in Tekken 2 and Tekken 3 called Slap-U-Silly, see Stone Fists
Slap U Silly, also known as Ninpo: Manji Kudzu in Japan, is a move used by Yoshimitsu since the first Tekken game. The move was originally named Stone Fists, however it was renamed in Tekken Tag Tournament. Both Kunimitsus have also been able to perform this attack since their debuts.
Upon performing the final hit, the user will become dizzy and fall over. The user can transition to Manji Spin Low Kicks after the first to third hits.
The move is a guaranteed combo, however continued attacks have a tendency to whiff as the user rotates slightly off-axis. Additionally, if the opponent is hit from the side, they will be pushed out of range, making the move potentially unsafe. It is however safe when blocked, with the exception of the final hit.
