Henry and Mudge and the Tall Tree House (Ready-To-Read, Level 2)

Henry and Mudge are in for a treat - a brand-new tree house! When Uncle Jake arrives with a trunkful of boards, Henry can hardly wait to start climbing. But when it's all finished, there's a major problem: Mudge can't climb! What's the use of a secret hideaway without Mudge to share the fun? It doesn't take Uncle Jake and Dad long to catch on. And pretty soon Henry and Mudge get a new tree house right where you'd least expect one!
