Blueprint: Blue Spraybot

Just to save some people some clicks, [item=169169] drops from either [npc=149847] or any of the Data Anomaly's that spawn when [npc=154982] is up which gives you the quest Discs of Norgannon.

This isn't a very good explanation. Crazed Trogg has an extremely low chance, less than 1% chance of dropping it. And it does NOT have a chance to drop from ALL the Data Anomalies, only the Rare Elites, Hogger or Razorclaw the Butcher (same loot table), Balnazzar or Captain Kromcrush (same loot table), Baron Kazum or Crowd Pummler 9-60 (same loot table), or Barron Geddon. 4 chances each time Discs of Norgannon is up at much higher percentage chances than Crazed Trogg.

Recipes appear in Pascal-K1N6's crafting UI but you have to unlock them. There's a tiny padlock icon to the right of the recipe title that indicates you have not yet unlocked that particular item. You can also check your progress on the achievement https://www.wowhead.com/achievement=13479.
