Totaka's Song

Totaka's Song is a song composed by Kazumi Totaka. The song appears in several games that Totaka composed the music for, and is usually hidden. This song is counted as an easter egg. Here is liated all the appearances of Totaka's Song in Animal Crossing

Animal Crossing (GCN)
K.K. Slider, or "Totakeke," owes his name to Kazumi Totaka. To hear Totaka's Song in Animal Crossing on the Nintendo GameCube, one must approach K.K. Slider when he plays music on Saturday night. The player must then request the song "K.K. Song". This is one of the three hidden songs in Animal Crossing, and without requesting it, K.K. Slider will never play it. Requesting "K.K. Song" will cause K.K. Slider to play a version of Totaka's Song, and afterwards, the player will receive a recording of the song that sounds a lot more like the version of Totaka's Song that players are used to hearing.

Animal Crossing (GCN) e-Reader Card Minigames
Cards P-13 and P-15 in Series 4 contain the "Who's Dunnit?" mini-game, which has Totaka's Song as its normal background music. This is a rare because most of the time Totaka's Song is hidden within the games, although one could argue the game itself is hidden in collectable card packs.

Animal Crossing Wild World
In Animal Crossing: Wild World, the song can be found in the same way as in Animal Crossing (GCN) ,but only in the Roost

Animal Crossing City Folk
You can do the same as in Wild World ,but you can find the song in another way. While being driven to or from the city in Kapp'n's bus, leave the Wii running without going through the text while Kapp'n is facing away from the player. This triggers a cycle of him whistling some of K.K. Slider's tunes, including K.K. Song (Totaka's Song).
