Just some dumb fun.

Making up dumb conspiracies about the show is just a way to pass time. Hence the /r/danieltigerconspiracy subreddit.

X is a fairly unflushed out character in the show. You really don't know much about him other than the fact that he takes care of O the owl. That leaves a lot of room to imagine what he might be doing with his spare time.

We know he’s taking online classes at Owl Correspondence School - but in what subject? Learning to pilot a jet airliner perhaps?
