The problem is that it doesn't sound like a pun, which is how, in my opinion, the titles should really sound if they're going to be puns. It sounds here like a simple (rather childish) title, despite actually being a pun, and there are much clevererer puns to use. This reminds me of titles like "Sharpedo Attack" or "Poetry Commotion", which work in a similar way, and this is not a very blatent pun like they were. Does Wally/Waldo still have a big franchise in America, because today's kiddies won't really know about it.
