Hmm... Weird how many Rare games have some sort of tool that you can use for zooming... Goldeneye and Perfect Dark both had sniper rifles, as did Jet Force Gemeni, Donkkey Kong 64 had an upgrade to the waepons that let you zoom, and then there's Banjo-Tooie and Star Fox Adventures.
Rare and their zooming.
Oh, and slightly more on topic, there is one guy on the flight control platform who has a pointy moustache like Waluigi's, but I think he's actually supposed to resemble some aeronaut (whose name escapes me at the moment.)
Go Moon!
