With avatar made:My newest addiction within niconico: caramelldansen, also known as ウッーウッーウマウマ(゚∀゚). Apparently this is a remix of some Swedish band song? For some reason, this got associated with a portion of the opening to Popotan, and resulted in a flurry of paradies. Very distinctive in the style of SD drawing and movement, with both hands next to ears mimicing rabbit ears. Highly addictive (i.e. 中毒注意 :heh:)
Edit: Darn you, wao. I finally got Danjou out of my head, and now...! (gotta go listen to more caramelldansen)
