"Beaver Fever" is sweeping Seaside Island. And no, it's not a disease, it's the popularity of the latest teenage pop star, Justin Beaver. Girls everywhere are going absolutely crazy over him, but the boys are failing to see just what makes him so great. Even Amy Rose and the normally paranoid Sticks the Badger are swept up in the Justin Beaver hype, and if Sticks is getting caught up in something she normally calls people out for becoming "pawns of the corporate fat cats," something is wrong. Sonic, Tails, and Knuckles know this, and decide to investigate just what's going on behind "Beaver Fever."
As luck would have it, Justin Beaver is in town right now doing an autograph signing, and he's scheduled for a concert that weekend. Unfortunately, their efforts to investigate are stymied by the fact that only music industry professionals are allowed where they need to go. However, Sonic comes up with a plan: He, Tails, and Knuckles form their own boy band, "Dreamboat Express," and pass themselves off as Justin's opening act so they can get into the music industry professionals only area.
They conveniently arrive just in time to hear the evil scheme: Justin's manager has embedded a method of mind control in Justin's music, intended to turn any females that hear it into mindless consumer zombies, which will make him filthy rich. Sonic and the others manage to escape and try to warn the girls, but they don't believe them because they're still smitten with Justin Beaver. However, now Tails comes up with a plan: If the mind control is embedded in Justin's music, there must be an opposite sound frequency to counter it. Thus, he invents a device he calls the "Measure-o-meter" to find it.
Of course, the Measure-o-meter requires that they get close enough for it to measure Justin's music, so at the concert, Dreamboat Express takes the stage and challenges Justin Beaver to a sing-off. They hold their own for a while, but then Justin hits them with a long extended note. This, however, tells Tails exactly what they need to counter the mind control, and Dreamboat Express quickly shifts gears to become the rock-and-roll band, "Dude-itude." Their rock-and-roll defeats Justin, and frees the girls in the audience, as well as Justin himself, from the producer's mind control.
Tropes featured in this episode:
- Absentee Actor: Doctor Eggman doesn't appear in this episode.
- Corrupt Corporate Executive: Justin Beaver's producer exploited him and his fans using mind control in order to make money off his sub-standard merchandise. Fortunately, Sonic, Tails, and Knuckles manage to foil his plans with their own music.
- Exploding Calendar: When Sonic, Tails, and Knuckles form their own boy band, they have to come up with a name, and a montage is shown. This includes the usual montage tropes, such as the Wastebasket Ball and Spinning Clock Hands. Then we see pages coming off the calender, only to subvert it, when Sonic reveals it was Knuckles:Sonic: Knuckles, stop tearing pages off that calendar!
- Furry Confusion: Uh, Sticks? "Fat cat" isn't nearly as pejorative in a world of talking animals.
- "I Know What We Can Do" Cut:
Tails: How are we gonna convince this guy we're in the music biz?
- Sonic pulls one of these in the episode.
Sonic: I know just what to do...
(cut to Sonic's Shack)
Sonic: We'll form our very own boy band!
Tails: Did you really have to bring us all the way down here to finish that sentence?
Tails: Don't worry. I know just what to do...
- Tails then does it later in the episode.
(cut to Tails' Workshop)
Tails: Since the mind control is embedded in Justin's music track, there must be an opposite sound frequency that could counter it. Just need to find it. Thus, the Measure-o-meter!
Sonic: It's fun to bring people a long way to finish a sentence, isn't it?
Tails: It really is!
- Immune to Mind Control: The mind control in Justin's music only works on females. Therefore, Sonic, Tails, and Knuckles are unaffected.
- Mind-Control Music: Justin Beaver's music has a mind control method in it designed to turn any girls that hear it into mindless consumer zombies.
- Mythology Gag: This isn't the first time Sonic has played a triple-necked guitar.
- No Celebrities Were Harmed: Justin Beaver is an Expy of Justin Bieber.
- Palette Swap: Justin Beaver's producer is basically the photographer's assistant with a wine jacket and a pink and wine checkered cap. Also, if you look closely at the crowd that shows up at Justin Beaver's concert, you can see a Lady Goat in a yellow dress, various pink Lady Goats in magenta dresses, a purple Zooey, various Lady Walruses in yellow dresses, a pink Lady Walrus in a purple dress, and various Percis with blue hoodies and boots.
- Start My Own: Sonic, Tails, and Knuckles start their own boy band so they can investigate the "Beaver Fever" phenomenon.
- Take That!: The concept and appeal of boy bands is amusingly torn apart and criticized, not to mention the fact that the star, Justin Beaver, is totally not Justin Bieber, a singer who is constantly mocked for various reasons.
- Who Would Be Stupid Enough?: Sonic states that the "Beaver Fever" going around is just a marketing ploy to sell sub standard music to gullible teenage girls, and wonders who could possibly fall for it. Cue Amy entering, covered in Justin Beaver merchandise.
- Who Writes This Crap?!: Upon the guys attempting to inform Amy and Sticks about this (to no avail), Knuckles relates how the producer described the plan right in front of them.Knuckles: Talk about lazy writing!
