She's drinking... she's transformed into a bunch-o-nanites... and now she has blue hair. Not a whole lotta to draw from and figure out "Just Who Is Donut"? So I took a more scientific approach:

Leasing time on a bank of supercomputers from the late 50s, I was able to crunch the facts (what little we know) on Donut and come up with the following profile:

1. Donut likes to drink
2. Donut can morf into a collection of 3 ultra small robots
3. Donut has either a) blue hair die, or b) a blue wig

These facts are inarguable (after all, ENIAC IS TRIED AND TRUE TECHNOLOGY). In addition, before the computer needed more coal to operate it's steam turbine engines, it spit out additiona Ragsnatch facts:

4. Donut has 'got her groove on'
5. Ironically, Donut would never actually eat a doughnut.

Ya gotta love the insiteful power of tech, as smuch as this little lady here! BRAVO DONUT! BRAVO!!!
