KA list for this episode (that I found at least on ANN): Eikichi Takahashi (also AD of this episode), Hiroaki Shimizu, Hiromi Naganawa, Hisao Muramatsu, Masa'aki Iwane, Toshio Mori, Yasuyuki Tada.

At least until 0:12 feels like it could be Iwane's work. I really am not familiar with any of the other animators, although it does sound likely that Takahashi himself handled the second part? I am not really sure.

EDIT: Asked Iwane and he said this was not his.
