I don't know if this has been mentioned before but...
During the episode "I think I am a clone now" where an evil copy of Wordgirl is stealing everyone's thesauruses.
For a brief scene we see Tobey in his rocking chair, reading one of them.
Unlike the others who are in class or in a library—he just has one at home that he reads during his free time.
I find this a nice bit of character continuity because it makes so much sense for him to be reading one—but why?
Well to find out we need to know, what is a thesaurus?
A thesaurus is a reference book used to find different words that have the same or similar meanings.
Consider that in the Wordgirl shorts where he meets her for the first time, he describes various synonyms.
Such as when Becky says she doesn't want her house "demolished" he proceeds to use various other synonyms of demolish, such as:
Or when he fought Wordgirl and he said,
And Wordgirl agrees and says,
"Tussle's good, I prefer brawl"
He knows his stuff when it comes to various words, not as much as Wordgirl considering she specializes in it but certainly enough to keep up with her.
It's nice to know that there's at least one person in the show that could match Wordgirl in terms of well... terms.
Makes them bonding in "Have you seen the remote?" even sweeter in my opinion because Tobey genuinely does like reading as much as Wordgirl.
