Used to be available from Liberty Tree Tavern but not sure if this is still the case now it isn't a character meal, also there is a generic souvenir cup which was available with Glow figures at Akershus and Concourse STeakhouse (now gone) when we were there plus Boma I seem to remember although we only bought it at the first two.
Flame Tree BBQ have them, you get your choice of which animal topper you want
The new kids drinks, they are a Tink plastic cup with light up Tink lights and I think there are Peter Pan ones too.....just about every restaurant has them
Tony's Town Square has a really pretty glass mug, and so does Liberty Tree Tavern. I got both on our last trip! 50s Prime Time Cafe has Mickey's Bee Bop Drink, which is in a plastic souvenir cup that has a plastic straw and cap. It has Mickey and the Studios logo on it. It also comes with a glow cube. I accidentally left mine on the table when I got mine, but my boyfriend gave me his!
