@jjbuttcrack,
Neopedia articles are numbered, but only up to 271 so far. Current Neopian times issue is 455. Games 664, 644 and 651 are all unavailable - most likely old sponsor games. User shops are by name, not number, and they are unlikely to contain anything that would be fixed anyway.
User profiles - moehog and ogrin are long abandoned accounts, while koi has been disabled. Neopets - moehog, ogrin and koi are all level 1 pets, although Koi is a Kau and Ogrin is a Kacheek.
Searching the Neopedia for Moehog, Ogrin or Koi returns nothing. (Says more about the limitations of Neopets search than anything else.)
Moehog day is May 14, Koi day is May 25, Ogrin day is 12/28. Don't see any pattern there.
