  Did it on Act 1 of Green Hill zone following the video below (video is not mine).
  
  Notes:
  -The sign comes down where the boss was during the last hit (in GHZ at least). (Mentioned by Slim Panatella).
  
  Credits to Shadiochao foe the video.

  This achievement is glitchy. Doing exactly this method and it won't pop.

  Could be that being in debug mode doesn’t unlock this. Tried in debug, wouldn’t unlock, so went into normal mode and tried again, and then it popped.

  Imposible to gey in debug, you have to play in normal to make it pop

  This can first be attained after you defeat the boss of the first act of Green Hill Zone. Playing as 'Sonic only' makes it easier as Tails can interfere when jumping with the signpost.
  
  The signpost will land wherever the boss fell so try to destroy him when he is on top of the large sunflower on the right (as this is where one of the monitors are). When the first monitor pops up guide the signpost to the 2 purple flowers on the left to pop the second monitor and unlock the achievement

  While I knew that Green Hill wasn't the only place this achievement could be done, I DIDN'T know there was a controlled outcome where you could nab two boxes without doing any work.
  
  (I don't think you have to be Knuckles to get the right angle, I was just going through his storyline.)
  
  This certainly surprised the hell out of me.
  
  

  
  POST EDIT: Whoops! Sorry, forgot I deleted this from my Xbox clips. I've added a YouTube link so this can stay up permanently. Don'tcha just hate that?

  What more do you want, for me to do it for you?
