By holding X or Y while using Samurai Fist, Jack can perform two secret animations that act as references to a scene from Episode XXXVI of the original series, where Jack and two Xiaolin monks battle and notice similarities between each other's skills:
•The first animation shows Jack performing the Water Beetle martial arts style.
•The second animation shows Jack turning towards the camera and performing the principal secret sign of the Xiaolin monks (a raised index finger and suppressed thumb).
