I'm playing Ed the SCV 2. I have the battery, red and black wires, duck head and pumpkins. And I'm stuck. It looks like I need 2 more items (or, at least there are slots on the combo thingy for 2 more), but I can't find anything more. I know I'm supposed to re-animate the head, but I don't think I have everything I need yet. I can also understand what the battery, wires and head are for, but the mini-pumpkins? LOL.

Oh, and what does SCV 2 mean?

I think you need to trade the pumpkin for a flute... try talking to the pillbug, which is near where you start.

I think:
S = Service
C = ??
V = Vehicle.
