Ten year old Bobby decides to head outside to a nearby park since the weather outside is great. On his way out, Bobby puts both the Ring of Age and the Ring of Youth in his pocket (he was previously told not to, but his naive judgment, given that he is ten now, told him otherwise).
While at the park, Bobby spots Jennifer's brother, Jimmy, along with a few friends. Although shocked at first (and worried that Jimmy would recognize him), the fact that his clothes have changed slightly as they shrunk to fit his body negated the concern. Jimmy then called Bobby over to hang out with the group (Bobby introduced himself as Tommy). Two hours later, it was getting dark outside, and Jimmy and his friends were getting ready to head to Jimmy's place. Bobby told them he had an errand to run and left the park. The sun setting meant it was time to return to Jennifer's and to return to his true age.
Just as Bobby attempted to put the rings back on to restore his age...
