"Cliff Hanger and the Grumpy Gourd Gatherers" is a great book in The Adventures of Cliff Hanger series by Livingston Dangerously. This issue teaches the hard sound of the letter "G".
Cliff is hanging from the cliff when's he hears two grumpy gourd gatherers criticizing every gourd they gripe form the ground. Upon hearing this, Cliff gets out his survival manual and learns to put on a gourd costume to get gathered by the gourd gatherers. Luckily, Cliff has a gorgeous gourd costume in his backpack, which he dons. The grumpy gourd gatherers mistake him for a gargantuan gourd. However, they think it's way to big. So, they throw it off the cliff, causing Cliff to grab back onto his branch.
