Did you ever notice that there were at least three episodes where Wally has a job that involves ice cream? "Wally, The Businessman", "Eddie, The Businessman", and "Wally's Weekend Job". It seemed to be a recurring theme like Beaver and new bicycles. LOL

Yes, there were several episdoes that were "clones" of other episodes.

Probably because by then they were running out of ideas so they modernized older episodes.
