Fixed.
I was rather tired when I wrote that.
I think the flavour text is fine overall, but I'd suggest a few changes.
Firstly, I don't feel it needs the bit about the gerenuk, so I'd cut it out. Secondly, I think "vegetation in shrub bushes" reads a bit wrong. I'd change the first flavour paragraph:
Dwarf elephants are the results of insular dwarfism on small island chains in the warm regions of the world. Grazing in matriarchal herds of up to 20 individuals or smaller bands of sub-adult bulls, they roam the scrub plains of their fortress-like islands in a near-constant search for food, using their trunks to feed upon the sparse vegetation of scrub bushes found dotting their habitat. While some sea-faring traders attempt to capture dwarf elephants as exotic goods in foreign lands, the natural flightiness (due to many island predators, usually large eagles or monitor lizards, being all too willing to consume the tiny elephants) and fickle diet (mostly endemic shrub bushes of the islands they inhabit) of the species makes them generally unsuitable for such ventures.
A dwarf elephant stands about 3 feet at the shoulder and weighs 300 to 500 pounds.
Thirdly, the
pygmy mammoths were 5'+ at the shoulder (the pygmy woolly mammoth was pretty big, being 6-8 feet tall, it just wasn't as big as a regular mammoth, being roughly 2/3rd their size).
So I'd recommend using the Large version of these dwarf elephants for their stats, how about changing that bit to:
Dwarf Mammoth: A similar species of dwarf proboscid living on some temperate and cold islands. These animals are roughly twice the size of a dwarf elephant, being 5 to 7 feet tall and weighing around 2000 pounds. Use the stats for a dwarf elephant that has been Advanced to Large size.
