This is amazing. There's this little song that you probably know from either Mario Paint or, more likely, Animal Crossing. In AC, it's called "K.K. Song" and it's one of the hidden tracks you can request of K.K. Slider, or, Totakeke, as he's known in Japan.
The song is something of a trademark signature of Nintendo composer Kazumi Totaka. It has been found in several games spanning a decade, from the SNES to the original Game Boy all the way to the DS. Mario Land 2, Link's Awakening, Yoshi Touch-n-Go, and several others.
The video back on that link shows off all of the known appearances... and also has this weird unedited television show vibe, which I don't get at all. It's like live TV, but done without caring what the host was doing throughout the shoot. I'd love to know who produced the video. And why. It's almost as if they weaseled onto some local station's morning news interview set. If that sort of thing is cool on the internet these days, holy hell do I have something new to do with my weekends.
Anyway, in most cases, the song is absurdly hidden and can only be located by pausing the game in a certain area and waiting for three minutes. Only then does the short little ditty play. It's insane. Makes you wonder how many more goofy things are secreted away like this. The ESRB will never find them all! This reminds me of when "easter eggs" actually meant something, before the whole concept was turned into a marketing bullet point.
But what blew my mind was this:
Kazumi Totaka's name would be more properly spoken in Japanese as Totaka Kazumi (family name first).
Which could possibly be abbreviated as Totaka K.
Which obviously became Animal Crossing's Totakeke.
