Sketching Event! Dokuro-chan! / Bukibuki-goshigoshi Battle! Dokuro-chan!

Sakura, Dokuro and Shizuki are on a school trip where they are asked to draw the scenery, but not without Dokuro harassing him most of the time. After Dokuro and Zakuro are scared of a "monster" they read about in a myth book, they then want (and force) Sakura to join them in the bath.
