I Have A Theory About Yellow Guy

I have a theory about Yellow Guy

In the 6th episode, Electricity, we see Yellow Guy go up those stairs, right? It’s even suggested he has been up there before - but hear me out. What if he and Lesley were always up there in the attic to begin with? Here’s my evidence: Yellow guy is shown to have undeniable intelligence when he is fitted with new batteries. His previous ones were old and “moldy”, so that suggested he never changed them. This also suggests that there was a time he had fresh batteries and this was not the first time he had acquired this ‘intelligent’ state. This could imply that as time went on, as the battery ran out, his intelligence started to deteriorate, and so did his memory. This also makes me believe that the “Big Boys Room” and the “Bigger Boys Room” were used to accommodate Yellow Guy’s mind. The higher the levels, the more ‘smarter’ they were, which makes me believe that as Yellow Guy grew ‘less smart’, he moved down each levels, going from Lesley, to the Bigger Boys Room, to the Big Boys room, and finally to the ground floor with the trio we all know and love. Adding onto that, did you notice that Yellow Guy was absent from these rooms? Red Guy and Duck was there, sure, but they seem to recognize Yellow Guy as a returning character. They even say he’s “Missing out” and he has to “Keep up”, which could suggest he had been away for a long time (due to his intelligence diminishing as prior mentioned). Lesley mentions that they are all replaceable, and that she “has plenty of backups”. But if that was the case, why is there multiple Red Guys and Ducks and only one Yellow Guy? This is here where we continue to theorize so buckle up. Lesley and Yellow Guy are obviously linked. With several evidence of Yellow Guy being Lesley’s son, David (Her saying “you’re not my real son”, Yellow Guy’s dream scene in the episode “Transport”, the photos Duck has in the episode “Family” etc. etc.) we can already see she has an attachment to him. There is also evidence that she is not the one in full control, with her felt like appearance and the fact that when we first see her, she states,

“Batteries can be replaced,

but some things stay the same.

No matter how we twist and turn,

we're still dancing in chains."

The first line is an obvious callback to Yellow Guy’s situation: unlike the other puppets of the trio, he requires batteries to function. Or at least, think freely for himself. Kind of like a toy. But he himself is not replaceable. That’s why the other levels do not have a Yellow Guy. So he “never changes”. But Lesley continues, using the inclusive pronoun, “we”, to suggest that he and Lesley are in the same position: Trapped as puppeteers for a greater being. Both of them had been in discomfort, fighting for independent control, suggested by the phrase “twist and turns” showing constant change of path, creating a sense of restlessness. But at the end of the day, both of them were still puppets “in chains”. When Yellow Guy leaves the ‘highest’ floor, it is shown that there are more stairs, which hints there being more ‘intelligent’ beings, possibly the puppeteers (aka the producers of the show and Roy as shown by ending credits). This could probably answer the question on why Lesley had the book (which has been widely believed to be their escape plan) that Yellow Guy had written in his own language and gives the show a lot more lore.

So my conclusion? Yellow Guy and Lesley used to conspire how to escape the puppet universe together in order to break free, but due to negligence on changing batteries, Yellow Guy was eventually used just as just a puppet for Lesley to replace her lost son and as a form of entertainment to preserve the memory of David, while Yellow Guy permanently loses his memories, succumbing to the inevitable fate of becoming a puppet more the wider audience.
