Connie the Cow episode "Connie and the Diamond" (triple-length episode of children's TV series; Existence confirmed)

I was looking up the Connie the Cow article on Wikipedia and read there was one triple-length episode. The rest of the episode list wasn't filled out on Wikipedia (only 18 episodes were listed at first), so I had to fill out the rest myself using my 2011 Connie the Cow Season 1 DVD and the rest of the episodes from Starz. However, the triple-length episode wasn't listed anywhere, so I had to keep searching around the Internet for a list of episodes until I got to TWC Central's website, where it listed "Connie and the Diamond" as an episode (it doesn't have a picture on the left, and the big text simply says "Connie the Cow"). However, that one wasn't listed on any episode lists, so I'm assuming "Connie and the Diamond" would be the one triple-length episode and series finale, but I can't tell if it ever aired on Noggin or if the episode itself even existed in the first place, since most other sites that list episodes for this show don't have it. If anyone finds any info about the "Connie and the Diamond" episode, bring it up in the comment thread below.
