Funny but the purple cart reminds me of the gift cart which used to be located at the exit of Walt Disney World's Haunted Mansion -- Madame Leota's caravan named "Varda." It was originally conceived as part of a potential attraction called "The Museum of the Weird," but when that wasn't approved the design was repurposed to sell merchandise.
Frankly, with a few added elements and some freehand decorating, it probably would make a nice Varda!
