He made some selections on the Chroniac:
He decided to make the changes happen over a long period of time. Gradually, the changes would come into effect. He first decided to change the height fields. Every day, Jay and Dan would shrink one inch and this height would then be transferred to make Sean grow two inches. Every day, Jay and Dan would loose one percent of their body mass, while Sean's would increase by two percent.
He clicked the icon to confirm the changes. Let the fun begin!
