Anyone know anything about the custom squishmallow store at greece ridge mall?

So my bf went to greece ridge mall like, last week. He said there was a hole in the wall store in there to make a custom squishmallow. I collect squishmallows so im incredibly interested. He said wed go today but its to cold so im trying to find it online cuz i figure i can just order one. But i can't find it in the directory and my bf doesn't remember when the store name was.
