Did I miss this icon? (Sakura poro)

Hi, some weeks ago I saw this icon: (http://vignette1.wikia.nocookie.net/leagueoflegends/images/9/91/ProfileIcon1626.png ) on the PBE page of the wiki but after being updated with newer content, I never saw it in the live client store. Did I miss it or is it planned for a future event? Thanks.
