I'm so sorry to hear this.
My best advice is to make a makeshift rocket to put the frog's corpse in. You can find many tutorials on how to make homemade rocket fuel. I suggest you get PVC Tubes for the right mix. 1 PVC Tube to put the frog in, and the other tube for the "Fuel". A cone on the top would help a lot.
I'm not a rocket scientist, but weather conditions may influence the launch of the Frog-rocket-corpse program.
Rest in peace. TO THE MOON!
