As a project to raise funds, the Association of Zoos and Aquariums offered their member zoos the opportunity to commission several  toad donation sculptures to celebrate 2008, " the Year of the Frog." 
Consequently , interactive sculptures similar to the one below which is at the Fresno Chaffe zoo in California, are collecting coins and dispensing wisecracks at zoos in St, Louis, Nashville, Fort Worth and  at Wisconsin's Henry Vilas Zoo.  The money the sculptures accumulate go to improve amphibian habitat.
