Which iconic '90s TV character was supposed to be a one-off?

I'm not sure how to adequately explain to a young person today what it was like when a TV character would get popular back in ye olden days.

Sort of like going viral, except instead of them filling up your social media feed the local Kmart would be flooded with books, toys, and games all featuring your favorite character saying the thing they always say.

And just imagine what the world would have been like had this been a one-time-only character, as it was originally intended to be. Frankly, I'm not sure I want to see what's happening in that timeline.

See if you can name this '90s character that was almost not iconic.
