WHO CAN DO KIM-BOP BETTER THAN A FROG CAN ?

These were sketches for a potential restaurant  icon... a frog character  for a Japanese place.  I thought it was an odd choice, but after looking around a bit and a little searching on the internet, a lot of Japanese restaurants like frogs for their imagery.  It has to go back farther than Sushi shops for Americans.  The frog must be a symbol having to do with food or fortune or Japan.
