Who can earn Carbon Rods?

I think Plopper can too but I haven't gotten that far in his quest.

Pie man - 8h
Fallout boy - 4h

as far as i know

Spider pig 8hr

I'm surprised that Milhouse's superhero skin doesn't earn Carbon Rods.

Me, too! I was hoping it would.

Also, I don't have fruitbat man, but I'm guessing he also does not earn carbon rods. (But there must be some point to the vigilante character collection, right?)

Fallout boy earns 10 for a four hour task.

Fruitbat Man can fight the prisoners that come with Burns jail
