The opposite of luffy. The legendary enemies of planet earth who utter ancient curses and create powdered smoke from fire itself. If you see a Yfful, do not run away. They are misunderstood creatures, prone to anger issues, and have problems sitting still. They look like regular people, but if you make them mad you might end up dead.
"I'm pretty sure Ellen's a Yfful."
"Don't make her mad or she'll kill you!"
A sea monster quite similar to the Loch Ness monster and the Ogopogo. The difference is that the Gogo Logo lives in Gull Lake, Alberta, thus being named Ogo with the first letters G and L. Nobody has never seen it but we know it's there. *Wink*
"I'm going to Gull Lake today."
"Look out for the Gogo Logo!"
