Pia just can't do it, she is too afraid to sit on the horse properly. The pump can't do it either, the horse can take too much. Unfortunately, the fingernails are the only thing that can help her to conquer the horse.
Gabi blows up a nice swimmring at first. She makes herself comfortable on it. As soon as it is really tight, she sits on it and starts to inflate 3 beachballs, which she stresses a bit with her fingernails.
