What do you want to overthrow today?
Okay, no.
Showing the rod.
This is your weapon. Make it what you want it to be.
Show various bits of gameplay footage where it's immediately apparent what the rod does, perhaps show a few addons with appropriate footage.
Or:
Rod with shell.
Want to take off the kid's gloves?
Remove shell from rod, show gameplay footage.
Or, what Nintendo will do:
Showing lots of people doing things with the rod instead of the appropriate tool (e.g. fishing, shooting, cooking), show the words "coming [releasedate]" and then the logo, no gameplay footage at all...
Yes, I have a feeling that's what Nintendo will do.
