Spelling

The other day I was sitting at the computer and Chance asked to come over and type. So I opened notepad, he climbed on my lap and started to type. We have done this before and mostly he just types random keys and talks to me about what he is "typing". This day was a little different though, he kept talking about the zoo and telling me that he wanted to go. I told him that there really isn't the same kind of zoo here that we have in New Orleans and maybe we would go to the zoo when we got back to NOLA. He wasn't happy about this answer and after a minute he got really focused on his typing then pointed at the screen and said "I want to go to the zoo!"
When I looked up this is what I saw:


along with all his random typing, the word zoo.
