Wigs are common head items that can currently be purchased in the Penguin Style, Snow and Sports or Costume Trunk catalogs. Originally, they could only be purchased from the Big Wigs catalog, but they were later moved into the Penguin Style and other catalogs mentioned above. The wigs mannequin for icons was changed on January 31, 2013.
- The Clown Hair is not considered as a wig, although it could be purchased in the Penguin Style catalog during Halloween. It also does not have a head in the icon like the other wigs.
- Some wigs can be found as costumes for Stage plays, like The Sidetied, The Fern Fuzz, Alaska's Explorer Hat, Grumpunzel's Beautiful Braid, and Ruby's The Movie Star.
- The catalog Big Wigs merged into Penguin Style in January 2009.
- Most of the wigs' names have "The" as a prefix.
- From October 25 to October 31, 2007, a vote was held in The Penguin Times to either have wigs stay or go. The majority voted for wigs to stay.
- Strangely, some wigs like The Funktastic do not have the new wig icon after the update that occurred in 2013.
- Some items like the Lab Goggles have a wig icon even though they are not wigs.
