As title asks. This is yet another one for far, far down the pipeline, if ever it is even considered.
While the only way out into the world as of 0.1.8 is iconic, it is also in my opinion limiting, and it denies Mrs. Slitherss her chance to really flesh out as a character.
I would like to propose a possible secondary path we can take to meet the world, wherein the student plays by Mrs. Slitherss's rules, and in fact can come in from Recess without necessarily making her mad, and earn a stern lecture from Mrs. Slitherss for having gone near the door, yet not necessarily hurting us.
Then she could assign us to a field trip to see the parts of the world that *she* wants us to see, and as we take off, the Juice Galaxy logo could happen like it does when we play normally. Mrs. Slitherss could share her outlook on the world, tell us some world-building elements, and we could get a chance to look at her softer side.
As for how we would go on to explore the world freely from this... I don't know. This game is great already and there's no need for this; if this were implemented anything like as described, I'd be so elated I say it's dealer's choice. I would like to suggest that perhaps we could just jump out of the "bus" at any time, fly off, and then she could say "worst student ever". Alternatively she could send us into the world to process and refine juice, and then when we get mad her monologue could change to demanding us to give up our refined juice.
This is all in pro-Slitherss excitement; please take it well.
