This is one of the few instances where Pop appears without Cub. The others are his BBQ smoochie, Something Fishy, and Milk Pong.
This is one of the few episodes where Pop is missing his pipe for the entirety of the episode.
This episode gave the announcement that Happy Tree Friends will be back with new episodes, as shown by the message in the end. The episode was later confirmed as Clause For Concern, as the washing machine scene was a clip of the episode.
This is one of the few episodes in which there are no deaths (though a small amount of blood can be seen when Mime hits the straw).
Despite the short being titled "Tunnel Vision", this video has no references to James Bond. Some viewers on YouTube expected the 'tunnel vision' gag based on James Bond, but that did not show up in this video.
This episode makes The Mole another character who appears in more than one HTF Short and survives all of them. The other character is Mime.
This episode might take place chronologically before Take Your Seat, since it is in the same place and Mime is sitting exactly where he sits in Take Your Seat with the same drink, although without the eye injury. The only exception is how in this one, most of the seats are empty (however, the movie could have been over and everyone except him left, but The Mole would have most likely stayed since being blind might have made him think that a movie was about to go on).
This is the one of the few episodes in which there are no character noises (Mime and The Mole are both silent characters). The others are Mime's Olympic Smoochie and Without a Hitch.
There are no female characters in this episode.
Mime's injury is similar to Handy's injury in Spare Me, which coincidentally was also caused by The Mole.
