• Sink the Prototype Punch Card into the Alpha Punch Card to get Half a Password

The Other Half

• After getting the Nonsensical musings, sink into it a Stamp #64 and a Stamp #512; you will get a Beta Punch Card

• Sink the Beta Punch Card into the Gold Punch Card to get The Other Half.

Complete Password
