Sumikko Gurashi
Sumikko Gurashi debuted in 2012 as a bad character who prefers to hide in a corner. "Penguin?" (with a question mark in its name) is a penguin who is unclear if it is indeed a penguin; "Tonkatsu" is an uneaten pork cutlet; "Neko" is a shy cat; and "Tokage" is one of the last dinosaurs. The series has spawned toys, books, stationery, games, and now a film.
