Confusing tidbit from SatAM opening

[XabinOtter]

So, looking at the opening for SatAM, I noticed that there's this humongous (what we call in the furry fandom "macro") fox Robian seen just before the gang infiltrate Robotropolis through the grate, but I don't recall ever seeing it or any other giant Robians - or giant Mobians, for that matter - in the actual show. What do you think this could mean?

It's not giant, it's in the foreground. If you know about perspective, you'll understand why it's bigger than the characters in the background.

This isn't confirmed to be the case, but I like to assume that the Robian is

Spoiler: show

Cat. Remember when he was captured in the episode that introduced him? He was never seen again, so I assume he was roboticized.
