For those who had to Google it, myself included:
"My Frogger Toy Trials is an action video game developed by Konami Computer Entertainment Hawaii and published by Konami for the Nintendo DS handheld video game console. It was first released in North America on November 13, 2006, in Europe on February 23, 2007, and in Australia on February 2007."
So it never got a Japan release, but this find of yours suggests they were planning for it. Is there any more text or is that the lot? It's not a lot.
Is Toby Inc a reference to a toy company or something?
