101% Spooky Whizbang With Henry And June
Henry and June's 101% Spooky Whizbang was a Halloween block that aired on Nickelodeon from October 2nd, 1999 up until October 29th of that year. This block was hosted by Henry and June from Nick's own KaBlam! Kablam Creator Mark Marek Animated segments for the block, but only a few have been recorded and only one is on YouTube.
In July 2012, YouTuber TheVHSkid76 uploaded commercials during that time. In doing so, he had a 15-second segment where Henry and June are at a baseball game. This also contained the commercial to the segments. The video can be seen here: https://www.youtube.com/watch?v=bm_yQXEm1F0
In July of 2019, Youtuber movieman95 discovered a barn dance segment. This depicted Henry & June at a Halloween barn dance. The 1st segment is about what makes it so spooky, the 2nd involves Henry pestering June into dancing with him only for a block to fall on Henry. And the last one involves June being possessed by a "Evil Spirit". The video can be seen here: https://www.youtube.com/watch?v=0JaErE0B_kI
Halloween Party: It is believed that a segment where Henry and June are at a Halloween party is deemed a segment. The screenshot shows Henry and June standing behind a party-goer who is dressed as a ghost with a banner above him saying "HAPPY HALLOWEEN"
It is unclear if Nickelodeon or Mark Marek will ever find or release this short.
Classroom: Only the first 3 seconds of this segment were found by JackIsCool TV (It doesn't mean that the whole thing is found yet). It shows Henry and June in a Classroom at night for unknown reasons. June points at Henry, presumably blaming it on him then explains the show the viewer is about to watch.
Again, it is unclear if Nickelodeon or Mark Marek will ever find or release this short.
Campfire: This segment involves Henry and June going camping, and no, not like in the episode "The KaBlair! Witch Project". After a few minutes of talking, Henry gets crushed by Mr. Foot. The segments existence was confirmed by and revealed by YouTuber Khalil The Retro Guy when he uploaded a series of commercial breaks from 1999. The video can be seen here: https://www.youtube.com/watch?v=uu8ygYIOBjI
Though partially found, it is unclear if the whole version sees the light of day.
