It's hard to include vocab words

For the make belief comix assignment it is so hard to include the words from Bad Boy vocab. This is because when I put in the dialog, there isn't any words in that chapter that were on the list. This makes it hard to include them in the comic.
So now we have to make up that Walter says something with a word in it rather than just take it from the book. Now we have him working with an apparatus that helps him talk right, and him wanting to yodel while his friend complains how excruciating it would be. This is annoying because it is hard to tell the story properly with including these words.
