That is so sad.
I know I used to catch the common toads/ bullfrogs here in the south and after handling them for only a few minutes they were really calm and would let me sit them like they were kissing or other silly stuff. They were always really mellow and after playing with them I would let them go. They would hop off like nothing happened.
I may be able to dig up an old photo here within the next few days that I took years ago of two kissing frogs.
