Their exploits begin after they escape from their pen and leave the farm where they first hatch. Unfortunately, they blunder into a raisin shipment and end up sent to the home of rich but lonely boy Brandon Wellington (Kevin Connors). He shares his newest "toys" with his tomboy neighbor Naomi (Jennifer Harte). Trouble comes when Brandon's stuffy housekeeper Mrs. Winters learns that she is terribly allergic to his diminutive reptiles.
