But instead of sitting on the egg like he was asked to, he puts it on top of the TV to keep it warm! Making sure he's got TV's hottest show on - ""The Eggs Files"", Eddie goes off with his friends to the BIRDBRAINZ arcade! Upon his return, he not only discovers that Abby has hatched in his absence, but that she's completely flown the coop! He tracks her down safe and sound, but not before learning the importance of taking responsibilities seriously.
