Part 2: Racist jokes in Spanish and Henry Kissinger quotes? This is educational!

Part 4: The magic square keeps on doggin’ us. Then: Grammar Ants! Grammar Corn! Grammar Apples!…Well, I tried to make the word “grammar” sound exciting.

Part 5: What’s the best material to make an elevator counterweight out of? Why, 25 pounds of mercury, of course!

Part 6: We finally get to the art and music portion of the puzzles, which we pass with flying colors. Couldn’t the magic math square have been this easy? Also: genetics.

Part 7: All those years of Robot Odyssey finally pay off as we solve a logic gate problem and save the volcano with our NANDs! Also, we finally get to see Dr. Brain’s secret experiment! It’s, uh…it’s…it’s a thing.
