Converting pumpkins into creep tokens (impossible)

As stated there are five converters, the 24 hour one can be used once per day the 13 hour one twice the 1,2 and 4 hour ones can be used multiple times as long of you wait the appropriate time period for the converter

However unless you buy the pumpkin booster (says seasonal currency but boosts the pumpkins from old houses) and have lots of old house that method is pretty much worthless.  

I just use the pumpkins from the event and season tracks
