Keaton's favorite b-day gifts

Among Keaton's favorite birthday gifts are a giant dog bone and this frog which was a birthday/anniversary gift from Marty. It's true that Frog is Keaton's favorite toy and he welcomed the new one. He and Ezra enjoy playing tug a war with Frog. I warn them they need to be gently after what happened to Frog Sr., but neither seem to take the warning seriously.
