Ensemble Dark Horse: Bunny. Despite only appearing this episode, she became popular amongst various fandoms, to the point some viewers have made various fan arts of what Bunny would've looked like if she were created properly.
Hilarious in Hindsight: The girls creating a fourth girl to help with their crime fighting becomes this in the reboot when we are introduced to an actual fourth Powerpuff Girl (and the original), Blisstina.
Cover Up:
Never Live It Down: Many fans will not let Blossom and Bubbles' behavior towards Buttercup in "Cover Up" slide (especially Bubbles, considering her Octi doll has made her behavior seem hypocritical), despite them being genuinely nice people for the most part.
They Wasted a Perfectly Good Plot: For an episode about security objects, it's quite bizarre that Octi isn't even mentioned oncenote unless you count Octi's brief cameo in the episode, as Bubbles' Octi doll could've been used as a good comparison to Buttercup's blanket.
