Below is a listing of various easter eggs within the game.
When you get a ship drop, extend the flash object and click on the upper left third of the black area (the cursor will change to a hand) to get the COMPASS-CHAN CLASSICAL DANCE PARTY.
It seems to have been removed on December 2014. Instead it was replaced with an image of a black colored ship girl with NO DATA printed on the anthropomorphise version. Since sometime around then till now, the NO DATA variant has now been removed for just a simple background, the voice line, voices and the caption but no actual image of the ship girl herself.
Some more information about it can be found here (albeit in Japanese only): http://kancolle.doorblog.jp/archives/35481633.html
As well some Google search results (albeit again in Japanese): http://goo.gl/L8BYDG Extended version of the "compass-chan classical dance party" music is found here: https://youtu.be/5TOzc4MfM9I
Non-functional repair cancellation dialogEdit
The "cancel repair" dialog is a function that is likely removed from the game. After placing ships in the repair dock, stretch the game window horizontally until there's a significant amount of wide black space on the left and right sides. Clicking on the space on the left will display the dialog, which does not actually cancel anything if "yes" is selected. Note that selecting "yes" also causes various bugs to occur.Re-clicking the black space again (by cancelling the window for the first time and clicking on the black space again) will sometimes show not an "undefined" ship but also a random ship that is currently in your possession (it can even show a ship that is currently going on an expedition).
Bug bouncing in the visual galleryEdit
The fairy (with the books on her head) in the gallery also has a bug on top. If you click on the fairy, the bug will bounce, and sometimes fly away. There has been a mini-game where some people see how many times they can click on the bug before it flies off (record on the Japanese Wiki seems to be 78 times).
Jumping Construction Girl Edit
This common easter egg only happens when you begin constructing a Ship girl, and clicking on that particular construction girl with a ponytail carrying boxes.
By taking apart the flash game client, one can discover features that are unimplemented, or have been cancelled.

- Kanmusu kcrzgndzraoddu
- Under kancolle server's directory, a folder with encoded file name as kcrzgndzraoddu contain sound files of unknown kanmusu, which can probably be seen as something dummy. More information maybe found here. (Seems to be removed now.)
