Commending Gaara for protecting himself and everyone else from the blast, the Mizukage reminded him that the situation would continually repeat itself if the clone wasn't stopped. Observing the ensuing clash, he states that despite Gaara's efforts and with his position exposed, it was now too late as another explosion was imminent and his sand would still be unable to restrain the clone. However, the Second was visibly shocked when the clone was captured and furthermore doesn't explode, yet after seeing it covered in a layer of gold, he suspected that the Gold Dust left behind by Gaara's father was responsible. This was confirmed by Gaara's explanation of how he incorporated the gold onto the clone, which melted and slowed it down, before covering it in sand saturated by hail to prevent the clone from heating up again. Upon hearing this, the Mizukage beamed at Gaara, stating that he was indeed a "golden egg"
