During the era in which Mr. Snuffleupagus was thought merely to be Big Bird's imaginary friend, a large portion of his appearances involved a scenario in which he was very nearly seen by the adults, either by design or some plot-driven mishap.
However, from time to time under, and often under unusual circumstances, Snuffy had been seen by the adults and other Muppets on Sesame Street. The Kids were usually an exception, most of whom could see Snuffy just as plainly as Big Bird could, including Jay who had aged up on the show and could still see him as late as age 13 in Episode 0415.
This page catalogues instances when a character encounters the supposedly imaginary Mr. Snuffleupagus prior to Episode 2096 when he was finally introduced to Big Bird's friends properly.

Bob soon recalls that what Forgetful is describing sounds like Big Bird's "imaginary" friend, the Snuffleupagus. They both figure that if that was indeed what it was, Forgetful couldn't have seen it and was imagining it- but yet Forgetful asks Bob what was standing behind them while they were talking.
