'''''Happy Tree Friends - Double Vision''''' was a [[Happy Tree Friends (franchise)|''Happy Tree Friends'']] interactive YouTube video published on the MondoMedia channel. It is a spot-the-difference game utilizing still shots of various ''Happy Tree Friends'' episodes, taking advantage of YouTube's annotation system, itself already used on ''[[Happy Tree Friends - Milk Pong]]''. However, since the annotations were retired starting on January 15, 2019<ref>https://web.archive.org/web/20181127223155/https://support.google.com/youtube/answer/7342737 "'''Update:''' We will stop showing existing annotations to viewers starting January 15, 2019. All existing annotations will be removed."</ref>, this game is no longer playable.

==Blurb==
The following blurb is displayed over a modified video of "[[A Sight for Sore Eyes]]" before the demonstration clip:

''It's time to''

''challenge your mind''

''and test your eyes''

''Get ready to play''

''Happy Tree Friends''

''Double Vision''

==Gameplay==
[[File:DoubleVisionDemo.png|thumb|An example level demonstrating how to use the annotations to find the difference in this shot from "[[A Bit of a Pickle]]". In this case, the difference is that [[Mr. Pickels]] is missing his hat.]]
The game was played using YouTube's annotations system. The player is given two images from one of the ''Happy Tree Friends'' episodes, with the image on the right side having one difference compared to the left. Choices were displayed in a 3x3 tile formation of annotations overlaid on said right-hand image, and clicking one of them would lead the player to an unlisted video determined based on whether they picked the correct answer or not. The video's length acts as the game's timer, meaning the player can still fail if they did not click any of the annotations when the video is about to end.

==Levels==
When this game was first released, there were only six levels, but by popular request, new levels were added on September 10, 2011.<ref>[https://www.youtube.com/watch?v=mufunyneawk Happy Tree Friends - Double Vision (New Levels) - YouTube]</ref>

==Trivia==
*The game could be easily cheated by hovering over an annotation and checking where the URL will lead to. If the URL is a different one compared to the other annotations (except for Level 11, which accepts either one of the two correct tiles due to [[Truffles]]'s placement), that annotation is the correct one.
