I had a similar experience of seeing that scene as a kid and it blowing my mind. I hadn't actually started the series from the first episode, and so when I first saw this as a rerun in 1999 I knew for sure that wasn't any Pokémon within the ~151 + Togepi advertised everywhere in the U.S. at the time.
It sorta felt like the feeling of seeing of a new Pokémon when information/internet wasn't widely available and everything was a still mystery was translated to the screen, with the characters not knowing anything about it either.
