I am attempting to put the Season 1 Episodes in chronological order.

I am doing them Chronologically based on events that happen.
Chronology is the science of locating events in time. An arrangement of events, from either earliest to latest or the reverse.
Example
Cannonball is before Poxy
Because in Cannonball Jumba shows Lilo and stitch the tricked out buggy for the first time. In Poxy the buggy has been around for some time.
