This looks like Screech's robot from the early seasons of "Saved By the Bell"!

HOW early are we talking here? Is this when Hayley Mills was still on the show?

I'm talking about the episode where Zack forgets Screech's birthday, so Screech is in a bad mood, so Zack plans to have a birthday party for him in school, except he wants to have it in Mr. Belding's office because that will be really cool, so he arranges to have the hall monitor fired (by tape recording him saying sassy things and playing it in algebra class), then gets Screech named hall monitor, and Screech brings his robot to school as assistant hall monitor, and then the girls call Mr. Belding's office and say they are a single person with multiple personalities who is lost at the mall, so he goes to get them, but meanwhile Zack is the only person who is at the party (because he got a hall pass from Screech), while everyone else is in detention, so he pretends to be Mr. Belding's secretary and gets on the loudspeaker and releases all the others from detention, so they can come to the party.

And I think that was actually BEFORE the Hayley Mills days.

IMPOSSIBLE. Hayley Mills was in the original series Good Morning Miss Bliss that spawned Saved By The Bell. There is no 'BEFORE the Hayley Mills days' when it comes to SBTB.
