Doctor Grundy lost his undies! His best ones, supersized! When a strong wind blows past Doctor Grundy's clothesline, away fly his undies. They land on a pirate ship, are blown on to Scotland, get a mend in China - but will they ever find their way back home? Another irreverent, fun story from McMillan and Kinnaird, Doctor Grundy's Undies blends rhyme, humour and an undie world tour with delightful colour illustrations.
