Skullette

The Skullette is one of the most famous and popular icons of Monster High.

Variants
Many variants of Skullettes have been produced.

Original Skullette
The original Skullette is a skull symbol with a bow, usually pink, in it's hair. The eyes of the skull have eyelashes.

Character Skullettes
The character skullettes are the skullette symbols used for the different characters.

To date, all of the doll characters minus Nefera have had their Skullettes released (though Toralei's and Operetta's were released later)

Frankie Stein:
Frankie's Skullette has a big stitch across it's head and bolts on each side. The signature colour is blue.

Draculaura:
Draculaura's Skullette has vampire fangs, elf-like ears and pink bows. The signature colour is pink.

Clawdeen Wolf:
Clawdeen's Skullette has a tuft of messy hair, wolf ears and fangs. The signature colour is purple

Lagoona Blue:
Lagoona's Skullette has scales on the head and fin ears. The signature colour is light aqua.

Cleo De Nile:
Cleo's Skullette is mummified with bandages. The signature colour is gold.

Operetta:
Operetta's Skullette has a mask just like Operetta's. The signature colour is velvet red.

Nefera De Nile:
Nefera's Skullette has not yet been unveiled yet. It is presumed that the signature colour will be nile blue, and that Nefera's skullette will be somewhat similar to Cleo's due to their sibling relation.

Other variants:
In the webisodes, the skullette on the Monster High crest logo has a crack in place of the bow.

Notes:

 * The skullette is used heavily in merchandise such as the Skullette Door Alarm and the Fortune Skulls.
