This humorous story tells how Dr Xargle instructs his class of aliens on the appearance and habits of "Earthlets" (human babies) before embarking on a field trip to Earth. Bath-time, feeding and changing nappies are all given a new slant by this alien guide to human behaviour. Jeanne Willis has also written "The Monster Bed", "The Long Blue Blazer", "The Tale of Georgie Grub" and "The Tale of Fearsome Fritz".
