I'm with those who've found the Kong merchandise underwhelming so far. Hopefully the cart at the exit will have more to offer than the displays in the gift shops, because simple tee shirts, generic-looking plushes, mugs, and shot glasses are not going to cut it for me. I'm also not a huge fan of the primary Kong graphic they're using on the shirts and pins, which is basically the exact same graphic from the teaser poster for the 2005 movie...
I'd like to see some unique designs on this stuff. Maybe that will come eventually.
