Ralph the mouse ventures out from behind the piney knothole in the wall of his hotel - room home, scrambles up the telephone wire to the end table, and climbs aboard the toy motorcycle left there by a young guest. His thrill ride does not last long. The ringing telephone startles Ralph, and he and the motorcycle take a terrible fall - right to the bottom of a metal wastebasket. Luckily, Keith, the owner of the motorcycle, returns to find his toy. Keith rescues Ralph and teaches him how to ride the bike. Thus begins a great friendship and many awesome adventures. Once a mouse can ride a motorcycle...almost anything can happen!
