Chrono Trigger - Frog Spekkio

Spekkio's weakest form with only 350 HP. However, most players never see it since your level has to be in the single-digits (1-9) before you reach the End of TIme.

A few tips:

• Run from any battles you aren't strictly required to fight.
• Wait for the execution scene. That lets you skip all of the fights and stealth sequences in the prison while still getting most of the items.
• Skip the conveyor belt section of the Derelict Factory. It's completely optional and has several fights you can't escape from.

For all this effort, your prize is a single Magic Tab.
