Mammoth

Mammoths were a species of huge prehistoric animals.

One universe's Jenny, who often dreamed of adventures her other selves were having, once dreamt of a Jenny who was riding “her mammoth” through the steppe. In what may or may not have been the same life, she also “charged the Mongol hordes” astride the same. (PROSE: The Genesis of Jenny Everywhere)

Colonel-028 of the Crew of the Copper-Colored Cupids once boasted of having taken on a mammoth by himself. (COMIC: Scaled-Up Soldier)

Another Jenny owned a mammoth fur coat, "with a multitude of interior pockets, certainly worth thousands if it were made of mink," but prone to emitting a "rich organic funk of mammoth fur in the rain" when wet. (PROSE: Cleaning Day)
