It's feasible that there really are 32 AAs in there...wiring groups of 8 in parallel and then connecting them in series will give you 6V. They won't be alkalines, however, and the amount of power you're going to be able to pull from them isn't going to be up to the standards you're used to. Cheap generic non-alkalines can be bought online for $0.08 each in bulk or $0.13 each for 40: http://www.cheapbatteries.com/generic.htm
