Tom Sawyer no Bouken

The original Japanese version of Adventures of Tom Sawyer. The level order has been changed in the English version (perhaps to avoid confusing players by starting with the rafting stage). The Japanese original's level 5, the pirate ship, is the English version's level 1, making the beginning of the game much more difficult and the plot non-cohesive.

Tom Sawyer is dreaming, and in this dream, he must save Becky from Injun Joe, traveling through six stages to get to her. He encounters various creatures, including a giant octopus, a giant alligator in the Mississippi River, ghosts and ghouls in a haunted house, and a dragon. He wakes up from the dream and finds himself in his Missouri classroom, where he finds one feather on his desk that had belonged to Injun Joe. It is never made clear whether or not the events of the game were real.
