Despite being released in December of 2005, Ogrins are still one of the newest species to enter Neopia. After 7 years, only four Ogrin characters have appeared in Neopia; two of them were Altador Cup players.
There are 36 different colours the Ogrin can become (counting Elderly Boy and Girl seperately). No Ogrin colour combinations had the option to remain unconverted.
Excluding their default avatar, there are no avatars that feature an Ogrin.
From the official Species page…
The Ogrin is the 40th most popular species to create; of non-limited/restricted pets, it beats out only the Moehog, Lenny, and Gnorbu.
