Hot Bath!

Sukuranburu ni nin sankyaku (スクランブル二人三脚) is the 161st chapter of the manga and the fourth chapter of the Hot Springs Obstacle Course Race Arc.

The girls hear voices from the other side of the spring and go to check it out, while the boys do the same. As they walk in opposite directions around a large rock dividing the two sides both groups miss each other. Mousse is anxious to see Shampoo naked, but Ryoga feels it is his duty to protect Akane from being peeped upon. Soon Shampoo discovers that the boys really are on the other side and makes a nude entrance which shocks Ryoga.
