That episode will have special guests. Fujigaya Taisuke and the rest of the regular Moshimo Tours group will get support by members of ABC-Z!!! (I'm not sure if it's all of them because the preview only showed Kawai, Hashimoto, Goseki and Tsukada)
They will be exploring the Disney Theme Parks in Tokyo.
