Shiver is Abbey Bominable's pet woolly mammoth.
Shiver is a baby blue and white fluffy pygmy mammoth.
"Her feelings being the kind not so easily punctured."
- The trademark for the name Shiver was requested in 2004, which makes it the oldest Monster High-related trademark.
- However, this trademark was more than likely for Shiver, a polar bear featured in Barbie and the Magic of Pegasus.
- On Abbey's box, Shiver's name may be mispelled with two V's. Not all boxes have the misspelling.
