Happy the Lab is back on the ranch, and it looks like he's up to his usual good-natured, bumbling ways! And, it just so happens that he has wandered onto Hank's ranch on a particularly exciting day: rain has finally come to their drought-stricken land, and--what's even more exciting--radio reports claim that there's a mountain lion on the prowl in their area! As the day unfolds, it appears that the mountain lion report was bogus, which is a good thing, since Hank already has his paws full surviving a bout of food-poisoning and a treacherous investigation of the machine shed, not to mention keeping an eye on Hap! Nevertheless, while Hank might find Hap a little exasperating at times, this latest adventure proves that a loyal lab is a great friend to have by our side when the going gets tough...then again, so is a cowdog!Happy Lab is back in town, and it looks like he's up to his old good-natured, bumbling ways. But, while Hank and Drover might find him a little exasperating at times, this latest adventure proves that a loyal lab is a great friend to have when the going gets tough.
