Jon and Liz have a three day beach vacation planned... without Garfield and Odie. Much to their horror, they have to stay with Aunt Ivy while Jon is gone. Garfield and Odie pray for rain, the only thing that can ruin their trip. Something Paddy the leprechaun seems to have brought with him while making his way through a tunnel. Trying to escape the wet weather in Ireland, Paddy has mistakenly brought it along with him. Now Ireland is sunny, and it's raining in Jon's town.
