I remember this one episode

where like in the place with the puppets there was this thing coming and they didnt know what it was and this guy I think his name was Charlie or something took a picture of it but it was a "cliffhanger" episode and it didnt show what "it" was and then the next episode it was this giant seed thing that turned into a flower... yeah I was actually kinda scared of it. Saw it somewhere between 1993-1995 not sure if it was a re-airing or not.

I was bored and TV.com listed synopsyes and it was a story arc in episodes 1631-1635
