It actually is possible to complete the game if the history report is in the future and lunchbox is in the prehistoric era. All Putt Putt has to do is oil Tobey the Train again after Putt Putt spends his first nickel.
The last entry in the Putt-Putt series to have Jason Ellefson as the voice of the titular protagonist.
The game was ported to the Nintendo Switch on January 3, 2022, along with Freddi Fish 3: Case Of The Stolen Conch Shell.
