Fooled again?

Pearl says, "Can you explain this?". "This is a mask from Indonesia, what do you make of the expression?", answers Pickle. Pearl considers and gives Pickle her opinion, "I think that looks like one mean dude". "Yes" says Pickle "and we thought all Earth people were meek and mild and a pushover for our forces to overcome, but now I'm not so sure, I must give my research some more thought". "But Pickle, if we send a negative report back to Ascalonia, our masters will terminate our stay here and I want to stay". "O.K., I will tell them inquiries are on going and we will get back to them soon", said Pickle. "Oh,thank you, Pickle" said Pearl. I know what they said because I eavesdropped and had my Universal Translator working. At least, that's what I think they said!
LITTLE FLY upon the mask/ Don't you wish you had worn a casque?/ For when I hit you on the head/ You'll wish that you had never been bred.
