Past Blast

Past Blast is the 7th Episode of Quest for the Crystal Potato

Plot
Dr. CrazyPerson has lost the map to the Crystal Potato in between episodes 6 and 7 due to Rob dropping it in "Hot Lava". He decides that the most practical way to retrieve the map is to go back in time to "June or July or Something" (Episode 2, The Above-Ground Cave) to when he still had the map. Meanwhile, Boston gets the same idea and chooses to join his brother, Charlie, who has a time machine in a time travel adventure that will take them to Dr. CrazyPerson's "Secondary Lair" where they will take the map. Dr. CrazyPerson gets the map and returns to his lair where he has a battle with Charlie. Dr. CrazyPerson and Boston end up fighting over the map, leading to episode 8.

Trivia
