Toads And Frogs Puzzle
in 2D

Here's a 2-dimensional variant of the Toads and Frogs puzzle. The rules are virtually identical. Frogs only move rightward or downward, toads can only move leftward and upward. A piece can jump over another piece of a different kind, provided the square on which it lands is empty. The goal of the puzzle of course is to cause frogs and toads to swap their positions.
