Pongo Mcwhiffy

Pongo Mcwhiffy is a character that appears in nearly every Murderous Maths book, and runs his own DeLuxe Burger Bar. He wants Veronica Gumfloss to be his girlfriend, so he uses his shower time (and neally the whole of the day) to invent new flavors for Veronica, which all of them she rejected. (And so Pongo has never had any shower.)
