When I watch "Pickles," I get the impression that the writers/producers were riding a lot on it. You see this in the opening music and just the overall feel of it.
But I agree: the Bubble Bass character didn't come off very well. We see him again briefly in "F.U.N.," which suggests to me that the writers/producers were possibly planning to make him a recurring character like Larry the Lobster or the Flying Dutchman, appearing in occassional episodes. But as we all know, his character was dropped.
Possibly the writers/producers had the same conclusions given here ("annoying as heck.")
