Well, I was young, I can remember that.  All other specifics I can't remember.
It must have been the early 90's, I can't remember first seeing it or last seeing it but it was on the TV.
All I can remember is them jumping into there holes and it being a really enjoyable experience.
I found this community when I was reflecting one day on the 'old days'.  I also looked for information on the series The Tick.  Anyway I still haven't downloaded any of the SPC or KNT episodes.  I am very much looking forward to watching the series again though as I can't remember anything about it.  And with KNT being a different story it is like getting 2 for the price of one.
