Luffy and Sanji are on a bold trek up the snow-covered mountain with Nami in search of a doctor since Nami got sick. Vivi and Usopp were not on the ship. Zoro was responsible to protect the ship, but he went to swim in the ice water to train but he got lost, again.

You went to search him, and after some hours, you found him sitting by a tree in the snow. He wasn't wearing a shirt or shoes.
