Well, to put it simply, it's a play on words.
My human has the weirdest sense of humor at times.
She started calling my nannybug (originally named Lokki) Bug. Then buggaboo. Then for fun, Bugs. Then came Bugs Buggy.
Sounds like a familiar character does it not?
For some reason seeing the two of us snoozing together as we often do, an idea came to mind. Instead of that funny rabbits catch phrase "What's up Doc?" she called us Bugs Buggy and the What's up Duck.
When it came time to name my blog, I thought, what better name than What's up Duck? I post what's up with me and the crew (but mostly me).
So there you have it.
Now can I have a salmon cube?
