A lesson in obedience ...Troo is not a baby, and he's not afraid to climb the biggest tree in the forest-even though his parents told him not to. But this tree isn't safe for anyone! What will happen if Troo falls? This is a Level Two I Can Read! book, which means it's perfect for children learning to sound out words and sentences. It aligns with guided reading level J and will be of interest to children Pre-K to 3rd grade.
