Be careful, Bendy cartoons never existed before the creation of the game! The dates and information I put in this video about these cartoons are not false, they're just taken from the "Wiki bendy" website (bendy.fandom.com), and I made a video about them. The dates are true, but it's the game itself that says that there were bendy cartoons in the history of the game, and I mean in the history of the game.
And the cartoon excerpts come either from the official game (BATIM) or from the official youtube channel of the game's creator (Joey Drew Studio).
The music is Bendy in Snow Sillies (Remix CG5)
