As for this information from the comments: http://www.wowhead.com/?npc=16368 I can guess that these enemies no longer exist. If so, this page should be deleted —The preceding unsigned comment was added by Renkien (talk · contr).

Fixed, they were in the Original Naxxramas, they will be conserved for historical purpose.
