Chrono Trigger: Jets of Time

You must collect the Gate Key, the Dreamstone, and the Ruby Knife. Enter the Tyrano Lair in 65,000,000 BC and defeat Black Tyrano, then proceed to Zeal Palace in 12,000 BC, enter the Ocean Palace, and defeat Lavos. If you are defeated by Lavos, you may watch the cutscenes and then use the bucket at the End of Time to re-engage Lavos or crash the Epoch into its shell.

• Gate Key: Grants access to Prehistory (65,000,000 BC)
• Dreamstone: Place on the button in Kino's cell in the Tyrano Lair to unlock the upper levels.
• Ruby Knife: Opens the sealed door to Queen Zeal's throne room and the path to the Ocean Palace.
