Trivia

 * The 3CHZ sticker appears to be a Wet Floor sticker, appearing in Sunken Scroll 15.
 * The PN3CRN sticker is based on the pine crane card from a Hanafuda deck.
 * The SM-SM character and SM-XX character stickers are parodies of Harvey Ball's smiley face design.
 * The BWTR-SQDLNS sticker appears to be based on a rotated Japanese Onsen symbol.
 * The MSSQ character sticker, used on all "munchy snacks" locker decoration items, is a parody of the Pringles logo (seemingly the one in use from 2002 until 2009).
