Missed when episode 2030 was uploaded a few months ago (or I probably forgot the episode number for that one).
The library scenes are interesting, in that it's probably the most Bruno spoke in full sentences (though they are all the same basic sentence - "No no no, I want to hear the story"). I thought he sounded a bit different in one of the "Hooper's Store gets rebuilt" episodes, listening to him here, he does sound more like that as well as how he did in other appearances (where his dialogue was often more brief).
Also interesting, when the kids vote, they all raise their hands but of course Bruno does not, but then when they ask to vote for who wants the grouch version of Snow White, Oscar asks Bruno to raise his hand. With his hands attached to the trash can, he couldn't raise his hand, but I feel they could have had his left hand unattached while Caroll had just his left hand in Oscar, Bruno was sitting so he could realistically let go of one handle without it looking odd, and would have been a solution to making him talk (though I am thankful for the rare talking appearance), having him raise his hand when everyone is asked to vote for the regular version.
Is it just me, or does Bruno have an extra invisible wire attached to his mouth in that one? There's a few quick frames where I feel I see an extra wire (or maybe the wire goes through the mouth and connects down in this one), maybe it's just some lighting or something else. With him doing a bit of talking there (as opposed to one or two words as usual), perhaps they needed an extra piece of wire attached.
While it wouldn't have been as funny, Bruno could have just placed Oscar's trash can in another part of the library or maybe even outside the building so Oscar wouldn't have to listen to the story while Bruno did. Or Oscar could have asked to get out of his trash can and walk away.
Micky seems Gina-like. If she had stuck around, I wonder if the show would have gotten Gina (past her debut) or if Micky would have ended up staying a long time and getting what Gina eventually got (would she have switched employment from the library to Hooper's Store?). I could see her being the one to start a day care, become a veterinarian, and adopt a child.
