One day, Weed tells everyone that it will soon be her birthday. Bill and Ben decide to get her a present - but what? As always, Slowcoach is on hand with sensible advice. He gives Bill and Ben a seed to grow into a flower. The flowerpot men find his instructions baffling. What is a seed-bed? Perhaps the seed needs to be planted in Slowcoach's bed? What sort of food does a seed eat? Fortunately, this comedy of errors ends very happily - with a beautiful pop-up flower for Weed. Children will enjoy the slapstick humour in this typical Bill and Ben adventure.
