Ratboy Genius goes for a ride in his little red buggy with his friends Happyman and Green Monster.
"Knock, knock!note pronounced "Nark, nark!" It's me, the Ratboy Genius!
I just came over to say 'Hi!'
I am... you know, the Ratboy Genius!
I hope we have a happy time!"
— The theme song
Ratboy Genius is a YouTube channel full of videos that are better seen for yourself than described. There are several ongoing series on the channel that are interconnected. The first and foremost is Ratboy's Kingdom, which follows the adventures of titular character Ratboy Genius and his exploits throughout his kingdom.
Darker and Edgier: While the earlier episodes were mostly short slice-of-life adventures, Ratboy Genius Dreams Minecraft has an actual antagonist in the form of Little King John and a more adventurous plot, which hilariously, grew the fanbase.
Happyman on the Red Planet and George is also pretty dark, especially once the connection between George, Frank and sue is explored.
Egopolis: The Ratboy Genius lives in The Ratboy Kingdom, near Lake Genius and the Ratboy Canal.
Evil Counterpart: Little King John to the Ratboy Genius. He's even a Palette Swap of him with a crown, and kidnaps Little Summer Solstice Baby to try and make her fall in love with him. Also, unlike Ratboy, he is way more Off Model then he is.
Exactly What It Says on the Tin: Quite a few characters fall into this, including the titular character. Leaping Friend is Ratboy Genius' friend who's always leaping, Very Tall Friend is his friend that's very tall, and Mr. Big Arms has big arms.
Funny Animal Anatomy: As one of the comments pointed out, Ratboy Genius looks nothing like a rat. Could be justified, though, seeing as it's unclear whether "Ratboy" implies that he's supposed to be an anthropomorphic rat or part of some species of ratlike people.
Genius Bruiser: George is revealed to be this before ending up on the Red Planet. He's the navigator for the Galactic Superheroes' space ship and he's also the muscle of the group, doing both with great pleasure.
Off Model: The intentionally bad and derpy faces for every character's 3D variant can be considered this, but Little King John is truly this. His body streches out, turns around faster then it should, and we see in the Dreams Minecraft series finale can even stretch out to Ratboy and the escaped Summer Solstice Baby while they're flying so far he is practically 5 times larger then them in the perspective. You can even see his head clearly far into the fly-away from the stop, and it's not until they reach the real world castle, which they were flying to, that you can't see him.
One Steve Limit: When Happyman discovers that a man named Bob ended up on the same planet earlier in the day, he immediately knows it's his friend Bob, and not anyone else by that name.
Perpetual Smiler: Happyman is constantly smiling, even when he finds out Little King John has taken over his factory.
Punch Clock Villain: Clyde works for Little King John, but when he's not at the castle he willingly helps Ratboy on his quest.
Recurring Riff: The theme song is woven into many of the compositions.
Synthetic Voice Actor: Everybody. All the time. Even the narrator. Though, seeing as the speech is intended to be text to speech, it would be hard to make the exclamations at the end audible, since they can't really replicate easily.
Take Your Time: Ratboy Genius's girlfriend had been kidnapped, yet he spends a day riding roller coasters.
Big Fish Boss in Galactic Superheroes. In episodes before his apperance, the superheroes would mainly deal with minor disputes that were easily solved. Then Big Fish Boss appears in episode three, invading the entire GalicSEA with his Fish Legions and tearing his enemies to pieces. "Nobody's safe! Peril in the galaxy! Big Fish Boss is a threat to us all!"
Villain Song: Little King John's Potato Knishes song, although it's more about the things he makes in his factory than about how evil he is.
However, he later got a little bit better one in the Intermission, largely about stealing Happyman's factory for himself.
What Measure Is a Mook?: Sets off the conflict in Galactic Superheroes 3. After Fish Eater snacks on a school of fish, the survivors report the incident to Big Fish Boss, Who's sent into a rage, saying that he needs every last fish for his master plan.
