Once upon a time, there was an old man who lived in a small village. He had three sons, but the youngest son was his favorite. The old man loved to tell stories and often told his sons stories about magical creatures and faraway lands. One day, the old man decided to take his sons on a journey to find these mythical creatures and lands. He told them that if they found one of these creatures or lands, they would be rewarded with great riches and fame. The boys were excited at the prospect of going on such an adventure and set off with their father early one morning. They traveled for days through forests and over mountains until they finally came to a large lake surrounded by tall trees. The old man stopped at the edge of the lake and pointed out something in the water that looked like a giant turtle swimming towards them. As it got closer, they could see it was actually an enormous sea turtle with bright green eyes! The old man told them that this giant sea turtle was called “Babu” and he was very wise indeed. He said Babu could help them find what they were looking for if only they asked him nicely enough. So the boys did just that –they asked Babu if he knew where any magical creatures or faraway lands might be found. Babu replied in a deep voice “Yes I do know…but you must first answer my riddle” The boys looked at each other nervously but agreed to try their best so Babu began: “What walks on four legs in the morning, two legs in the afternoon, three legs in the evening?” After some thought, one of the boys answered confidently “It is Man –for we crawl as infants, walk as adults then use canes when we are elderly” Babu smiled broadly before replying “You have answered correctly! In return I will tell you where you can find what you seek…follow me!” And so Babu began swimming away from shore while beckoning for them to follow him into deeper waters until eventually he stopped near an island surrounded by misty fog which seemed to shimmer like diamonds when illuminated by moonlight . Babu announced proudly that this island was known as Fairyland –the home of all kinds of magical creatures such as fairies , elves , trolls , giants , dragons , unicorns etc . He said if they explored long enough , perhaps even more amazing things would be revealed ! So without further ado , off into Fairyland went our brave adventurers ! As soon as they stepped foot onto this mystical land , all sorts of enchanting sights unfolded before their eyes –from lush gardens filled with colorful flowers & plants to majestic castles adorned with sparkling jewels & gems . Even more incredible were all manner of strange creatures & people living there -like talking animals & mermaids -each having its own unique characteristics & abilities . The boys were amazed at everything around them & couldn't believe their luck -they had stumbled upon something truly extraordinary ! After exploring for days on end (and gaining many new friends along their journey) eventually it came time for our heroes to leave Fairyland . But before doing so , Babu presented each boy with a special gift : A golden key which opened up any door leading back home from wherever one may wander . This way no matter how lost or far away from home one may get -one will always have this key handy so returning is never too difficult ! With heavy hearts yet filled with joy from all their adventures -our adventurers bid farewell to Fairyland (and especially dear Babu) before setting off back home once again . And thus ends our story today ……or does it ? For who knows what other amazing places await those brave enough (or lucky enough)to explore beyond our world ?
