Wakame Ambassador

The Seaweed Ambassador is a creation of Captain Byakuya Kuchiki of the 6th Squad. It was first introduced in the Colorful Bleach story arc concerning the Jump Fiesta when Byakuya proposed that squad 6's entry for the fiesta be taiyaki in the shape of the Seaweed Ambassador. Since then, the ambassador has appeared in the a number of omake chapters both in the manga and the anime. Among other appearances, it was Byakuya's entry in the sand sculpture competition during the Special Bleach on the Beach chapter. Also, during the omake in episode 236, Hanatarō mistakes a large figurine of the Seaweed Ambassador as an injured person while searching the Kuchiki manor for injured people. Rukia Kuchiki appears to be the only other person who likes the Seaweed Ambassador, although Rikichi has commented that he thinks the shape suits Byakuya.
