I know, as soon as I started researching I realized I was told the wrong species. There was a big brown fellow in the tank at the store that looked just like the brown guy in your pic, so maybe that tank was labeled for monkey frogs and he didn't realize this one was different. I don't know, but I'm glad I figured it out so I can learn how to care for this cutie in the right way.
He really does look amazing, my girlfriend has fallen in love with him, haha. But yes, he does deserve a happy home!
