This third episode starts with Strong Bad heading into his room to spend some quality time with Senor Fun Machine (AKA his Videlectrix console). In booting up Limozeen's Hot Babelian Odyssey (the first of many, many awesome Limozeen references), sparks fly from the console and Strong Bad realizes he's got to get the thing fixed. The only person in town who can do it? Bubs.
Next stop is Bub's stand, where we really get the plot rolling. Bubs can fix the console ... for a big bag of cash. How does one acquire these highly sought-after bags of financial freedom? Why, a battle of the bands brings in the dough! So, Strong Bad sets his mind on getting this thing started, which requires security, celebrity judges (a flyer to design album art for Limozeen is Strong Bad's ticket to get them to be the judges), and a venue, according to Bubs.
I won't go any further into the story, but if you've played the first two episodes, then you know the score. Items aren't what they appear (using Jalapeno cheddar cheese spray for graffiti? Only in the Homestar Runner universe) and it's basically one big goofy and comical time. Like the previous two episodes.
What set it over the top for me, personally, is all of the Limozeen references. And Strong Bad's awesome album art he drew when he was 8 years old. And Strong Sad as a pretentious rock journalist. It all came together to be what I think is the most appealing episode in the series to date.
