I'm not sure. With a google site search, I'm finding multiple instances of "whisper", both in templates/tables and in plain text. Also, it should catch variants like "whisperer" and "whispers" - which also leaves a blank. As an example, I searched for "helps" and "searches", and got all kind of variant results. I could only find the episode you mentioned through google - it's called "SM031: The Island Whisperer!". It also doesn't show up in the search results for "Island".

So... I have no clue. Report it as a bug to Special:Contact/bug with all the examples you can find.
