Other "Factions".

Bone carving, or maybe some kind of processing, under the keys of a piano keyboard, a dog waltz is played. Or who knows, maybe it's some kind of musical group :D

Piano, grand piano, upright piano: Bone-keys, pedal - the one at the bottom, Dog Waltz - composition, hammer - instrument, charge - tuning, navigation buttons - keyboard.

Student life: Charge - tuning/studying, Tusks - History/excavations, Pedal - spinning, Dogs - whirling, Hammer - hammering, Keyboard - computer.
Example: I'm sitting in the dorm room at the computer, I need to do my homework (physics), but I'm too lazy to dig up a paper. Oh well, forget it - I'll spin around the professor tomorrow and somehow get out of it.
