Tumbling toy system and its associated method of operation

A tumbling toy system, comprising:

• a guide track having two sides and a bottom that extend between two opposite ends, wherein said two sides are a first distance apart at a first elevation above said bottom;
• a tumble pin resting in said guide track that is free to tumble within said guide track, said tumble pin having a first length between a first end and an opposite second end, and a midplane between said first end and said second end, wherein said first end and said second end of said tumble pin cyclically contact said bottom of said guide track as said tumble pin tumbles within said guide track;
• wherein said tumble pin tapers from a maximum diameter at said midplane to a minimum diameter at both said first end and said second end, and wherein said maximum diameter is larger than said first distance between said two sides, therein causing said tumble pin to cyclically contact said two sides and become temporarily suspended between said two sides as said tumble pin tumbles within said guide track.
