My son loves Pete, especially on the Mickey Mouse Clubhouse show, but when we've gone to the parks the only merchandise we've found is one pin at Disneyland. Is there anything at WDW that is pete themed?
Not sure, but your best bet would probably be the big gift store in ToonTown....I think it is called County Bounty. It is connected to the Toontown Hall of fame where you meet all of the characters. In Toontown there is also "Pete's Garage", but it is nothing but a facade for the restrooms and water fountains. But it is a good photo op.
