Ep. 69: Will Yusuke Be Released From His Prison

Kuwabara and Botan also turns into stone due to saying hot as well. Kurama discreetly takes the key from Yanagisawa. Kurama challenges Kaito to a game of taboo in which letters of the alphabet become taboo one by one over the course of the game, waging their souls as their bids. Kurama surrounds himself with his manifested plants while Kaito goes to the restroom, emerging when only the first two letters are left. Kurama yells to scare him, but he manages not to cry out. It is until Kurama makes silly faces at Kaito that cause the latter to laugh, thereby breaking the taboo. Kaito loses his own soul, thus freeing the others. (Source: Wikipedia)
