The Curious Case of Frog riding Turtle.

So this has nothing to do with pop culture really, but I saw this ornament and it posed so many questions. First off, notice that the frog is riding a turtle. Why? Though the frog is encumbered with his gift, one would still assume that the frog could move faster than the turtle. Second, why has a frog domesticated a turtle for riding purposes? Why a turtle? Why not a lizard? and how did the frog domesticate the turtle? I realize the frog has been "humanized" because he is wearing a Santa hat, has a gift, and put a nice little bow on his pet turtle...but still, how does one train a turtle? and finally, where are these two mysterious reptilphibians going? Any thoughts?
