I believe the ladies Mr Toads' shirt is still available. I am not sure about the other one. We were just there and I was wearing my yellow Mr. Toad shirt, and the Santa from Canada stopped, saw my shirt, and said, "Well, is that a blast from the past!"
After the show, he even asked me where I got it. The shirt is a definite conversation starter, especially with old school CMs. It's good Disney is realizing the potential of the nostalgia market.
