After all Timmy doesn't wish them into the various forms they become when they're hiding out in the open.
Another question would be what could Goku and Superman do to them?
We already saw in the Channel Chasers movie the DBZ parody the large ki blast had virtually no effect other than turning them black.
And think about all Jorgon does without wishes. In one episode, they say they need Timmy to wish it for their magic to work...
But then in later episodes, they constantly use magic. I think they can morph into other shapes, or do minor things (like poof a single item or something), but wishes like "I wish the entire world were a comic book" requires Timmy to say it
