How can the adults fail to see Snuffy that whole time?
Ok, I was way too young to realize that Snuffy use to be a secret because this occurred in the 70s and 80s and I was born in 1990.
But anyways, how can they miss someone as huge and furry as Snuffy. Next to Big Bird, he's the largest muppet on the show as big as an elephant. Impossible to miss
And all Big Bird had to do was tell Snuffy to sit still and not go anywhere and get the grownups to see him. Unless he was shy or something.
Again, these episodes where before my time so don't judge.
