Twiggy is actually the latest of several gray squirrels that have been trained in succession. The Twiggy performing in this show is the sixth generation Twiggy and is 10-years-old. /Xinhua Photo

The squirrels are trained to ride on buoyant foam blocks, which are then towed behind a remote-controlled boat. Once retired, the squirrels become family pets. /Xinhua Photo
