In a grand old oak tree, deep in the heart of a sun-dappled forest, lived a lively squirrel named Squeaky and a cheerful sparrow named Sparrow. Squeaky had a fluffy tail and bright eyes, always bustling about collecting acorns and playing in the branches. Sparrow had soft brown feathers and a sweet voice that filled the forest with songs every morning.   One fine spring day, as the flowers bloomed and the forest buzzed with life, Squeaky was busy gathering acorns to store in his cozy nest. Sparrow, perched on a nearby branch, watched with keen interest.   "Hello, Squeaky!"
