Sumikko Gurashi debuted in 2012 as slightly negative characters who like to stay in the corner of a room. The characters include 'Shirokuma,' a polar bear who is sensitive to cold; 'Penguin?' (with a question mark in its name), a penguin who is unsure if it is actually a penguin; 'Tonkatsu,' a piece of pork cutlet that was left uneaten; 'Neko,' a shy cat; and 'Tokage,' who hides his nature as one of the last dinosaurs. The franchise has inspired toys, books, stationery material, video games--and now a feature film. (Source: ANN)
