funniest flying squirrel I've NEVER seen

I've been told I have flying squirrels in my yard but I have never seen one.  Friday I was sitting in the kitchen and saw one fly from the bamboo to the cactus!  I was so excited.  I crept out the bedroom door with my camera so as not to scare it off.  I zoomed in and lo and behold it was the funniest flying squirrel!   As you can see, it is NOT a flying squirrel.  It is a GIANT gross frog.  I wasn't afraid of scaring this thing off so I shot a few more pics as he sat stop the tall cactus.
