Why doesn't Snap get smudged by Rudy when he touches him? Or anything else in Chalk Zone, for that matter?
Yeah, but magic chalk has all the vulnerabilities of regular chalk, so it seems weird that this one is excused for unexplained reasons.
Isn't the reason they're usually in Chalk Zone?
It's possible that zoners and inanimate things in ChalkZone take on at least some of the properties of what they are supposed to be, and thus can no longer be smudged as that weakness of chalk is overridden by the new properties given to it. For instance, the reason Snap isn't smudged is because, although he's chalk, his skin is of the same toughness as human skin while his clothes don't smear because they share the same properties as their Real World counterpart, just with the whole being made of chalk added in the mix.
Something I've always wondered; where do the letters, punctuation, numbers, and the like go when they're erased? You'd think that'd be filling up Chalk Zone by now since, you know, that's the primary purpose of school chalkboards.
In the episode "The Towering Wilter", it's revealed they all end up at a dump in ChalkZone.
I can't find the episode Double Trouble and the ChalkZone Wiki is of no help, so I'll ask this now: is Craniac 4 supposed to be male or female? I know it's a robot, but what gender is it referred to as?
Given that there seems to be a 1:1 correlation between locations in the ChalkZone and the real world (you move 1 mile south in ChalkZone, you move 1 mile south in the real world), how does Snap keep finding the portals Rudy opens up?
It's possible that the portals give off an aura that zoners who are particularly close to the drawer and/or were drawn by a magic chalk user (to explain fanfics that involve Skrawl being able to do this as well if they exist) are able to track. It's not 100% accurate and nobody knows this is the reason, hence why they never bring it up in canon; they just think Snap is ridiculously lucky.
