Green Wilma is so determined to catch a tasty fly that she doesn't notice a family of galactic visitors to her pond. In a case of mistaken identity, the alien parents beam Wilma on board their spaceship while leaving their child, Blooger, behind. Poor Blooger, stuck on the bewildering planet Earth. Poor Wilma, hungry and confused (though also having the ride of her life!). Will the two be able to switch back in time for supper?
