The leprechaun suddenly realized his gold was missing, he had worked too hard for that pot of gold, he had spent the last few days making shoes for some bratty fairies, and now it was gone, he sat in his room (which was filled with gold) crying, there was barely room for him to sit, he did not buy the idea of keeping his gold at the end of rainbows, he believed the rainbow was basically a "steal me" sign and he wasn't wrong, all the other leprechauns had lost a lot of gold to greedy humans.
He set out to find his gold, he carried a bag of gold and payed anyone that had any information about the whereabouts of his gold, he was determined to find it by all means, but his gold was no where to be found, after several painful days of trying to find his gold, his room was now half empty, he had spent most of his life savings trying to find his pot of gold, but he wasn't ready to give up, not yet, he still had one last option, "THE GOLD SNIFFERS", these are leprechauns whose love for gold drove them to the point of being able to find gold anywhere, no matter how far away it might be.
He summoned the GOLD SNIFFERS, the only way to summon a GOLD SNIFFER is to rub a piece of gold in a certain area of your body that things are not supposed to be rubbed in, the process is quite disturbing, so, they came knocking on his door, they were quite crazy looking, but if anyone could do the job, it was them, he was happy to see them, finally, his pot of gold was finally going to be recovered.
After explaining everything to them, they agreed to help him, actually, they weren't going to, until he offered them all the gold he had left in his house, it was a lot of gold, the GOLD SNIFFERS had been known to always take payment before delivery, so he payed them, they left with huge smiles on their faces and the next day they came back with his pot of gold, which was actually a tiny fraction of the gold he payed them with that they poured into a pot, the GOLD SNIFFERS were mischievous creatures.
He was so happy when he heard the knock on his door, he had been waiting anxiously, he ran to the door excitedly in his limited edition shoes (which he made by himself), he opened the door and received his pot of gold, he was too excited to ask any questions, he just slammed the door and ran to his room with the pot of gold, he was finally reunited with his long lost love(gold).
He wasn't exactly the smartest leprechaun.
