Q: What do I do if I draw an UnGoal as part of Draw 3 Play 2 of Them while Cosmic Instructions is in play?

A: When Cosmic Instructions is played, it causes UnGoals to be treated exactly like Creepers, so if you draw one as part of your D3P2 play, you need to immediately play it and draw to replace to your mini-hand until you have 3 cards, none of which are UnGoals (or Creepers). Then Play 2 and discard the remaining card.
