Chrono Trigger – 011 – Fix the Masamune, Enter the Magic Cave

Alright, so we have the Dreamstone, both the broken pieces of the Masamune, and the Gate Key. Not it's time to get that thing forged by Melchior. We bring the fixed up Masamune back to Frog, who then let's us in on his back story, seems he's had some dealings with Magus and his subordinates before back when he was Cyrus, the human. We go get Frog's magic skill and then head to the Magic Cave, where Frog literally splits open the face of the mountain with the Masamune, revealing the entrance to the cave.
