Rangers Tom and Twigs plant carrot seeds in order to earn their Green Fingers badges. The carrots grow rapidly and oversized, creating a dilemma of how to harvest them. Zigzoo approaches the problem from underground, using his helping-hand gadget to push the carrots upwards. In so doing, he sends the carrots skywards - causing them to rain down on all and sundry. Thinking they are under attack from the carrots of doom, the friends retreat to the safety of the caverns to discover the real cause of the problem. In the end, something that at first scared them becomes harmless and quite delicious.
