Sealed Japanese LeapFrog game I found at a Goodwill

I found and bought some brand new sealed Japanese LeapFrog game called Oyako Eigo Step 9 Book #2, at a local Goodwill a couple years back for a buck. Anyone familiar with these Japanese LeapFrog games? Are these of any value for collectors?

As you can see on the back lable, it says "First Production Submission Sample Tag".

Where have I seen that Cat before... OH YEAH here

The last 30 seconds of that video were so awesome.

 

Are there any leapfrog collectors? It could be quite rare, but desirable it isn't. I would be surprised if you got any more then $50 for it.
