Hey there everyone! i kinda left this community a long time ago, tho i would like to share a theory in a full post. the theory is about how there are different generations of Rainbow Friends. i have mentioned it a few times.
Part 1: Blue's First Friend. Or was him?
While the animatronics are obviously predecessors, there's a little inconcistency that gives away a little information of the lore. Blue's First Friend is a photo taken in 1991 of Blue, and an unnamed child. one thing you might notice, is that according to merchandise Blue's Arm was made in 1992. But how could have Blue's Arm been created in 1992 if there's a photo of Blue from 1991? that's right, the Blue you seen on the painting next to Blue's First Friend is not the same Blue that chases you around in Chapter 1 and 2. Meaning that The Animatronics, The Picture Era Monsters, And The Chapter 1 Monsters are different generations of Rainbow Friends, you see how i specified Chapter 1? we are getting onto Chapter 2 now, with the help of 2 fellas, Yellow, and.... uh.... Yellow.
Part 2: The Yellow Family Tree.
As there is an unused Yellow rainbow friend in Chapter 1 that only exists out bounds, the tought of atleast 2 Yellows isn't to farfetched. That's Right! We are Talking about Yellow Senior! The Monster who everybody called Yellow before Chapter 2. Howewer, what if i told you, Both Pink and Yellow Senior are canon.
There are these butterfly nests that are mean't to represent the Rainbow Friends and they're size, causing many people to speculate how big Pink will be in the next Chapter. tho a thing that people ALWAYS forget is that the easter eggs to to Pink aren't mean't to tease Pink for the next Chapter, they are there because Pink was oringinally supposted to appear in Chapter 2(same goes for Chapter 1). but as you can see, Pink is depicted as bigger than Yellow, even tho thats not the case. also, there is no Cyan. this is obviously meant to be an odd to Chapter 1 and its unused monsters. meaning they technically are canon. yes, Pink and Yellow Senior, are implied to be canon. im not even kidding. Not only does this imply that once again, Yellow Senior is Yellow's Predecessor, but, remember Yellow's nest? Birds only build nests if they're about to start a family, witch Yellow is obviously not trying to do. Also, Yellow is the one that eats you at the nest, kinda like the baby birds. so, what if, the nest was Built by Yellow Senior, for Yellow. many people could argue that Yellow is a pterodactyl, but thats just not true. Yellow is reffered to as "Bird" in the game files, meaning they indeed are both birds. also, there's a voiceline of Yellow where he just says "Yellow", implying he might be calling for another Yellow. You may say the Rainbow Friends can't talk, But Blue and Yellow often say the phrase "Got you!" when chasing a player.
