Farmer Pickles asks Bob for some old Tyres to hold down a tarpaulin in his field. Bob agrees to drop them off on his way to the Lazenby’s. At the field, Scoop starts sneezing. Bob realises he has hay fever, and sends him home. Spud follows Bob to the Lazenby's, where he causes mischief with one of the Tyres. Bob sends him to the yard to look after Scoop. Delighted with his new job, Spud decides to find out what else makes Scoop sneeze. Bob finishes work and heads home, with Lofty carrying Spud's Tyre. Wendy returns to the yard with some flowers from Mrs. Potts' garden - a thank you for installing her rotary drier. Spud grabs them to see if they make Scoop sneeze. Indeed they do! Just then, Lofty returns. Scoop knocks into the Tyre he is carrying, which falls and traps Spud's arms, keeping him out of any more trouble.
