Bagel Company knows what's up!

Could you please explain it further, I have no idea what that's supposed to mean

It's like the phrase "open sesame!" This machine is used to open bagels, and there are such things as sesame bagels. It's like a play on words.

Hope that helps cause I didn't really know where I was going with that.

Ah, thank you so much, I didn't know where the phrase was from because I only know the German version of the story!
