Hairy Maclary's Caterwaul Caper

Hairy Maclary heard a strange sound,
a yowling,
a wailing
that echoed around . . .

What could be causing the caterwauling cacophony that brings Hairy Maclary and his friends running?

With yips, yaps, wrowls and howls, this story is an absolute delight to read aloud.
