Beepo is unable to curse as his blueprints specified that his expletives were limited to things like "Linguine!!" by his Japanese manufacturers. Here he is sleep mode, and recharging. He is dreaming about being able to curse. That is some random passerby robot. Perhaps he is literally a Movie-Extra Bot designed by a joint effort between Warner Brothers Studios and Honda.
I like the idea of Beepo being able to dream because it adds a Pinocchio element to his character. I think in his dream he is pestered and inconvenienced so many times and all he can say is "Linguine" and then he finally explodes in this way because this passerby does some tiny little thing.
