Resumen
A leprechaun has appeared inside grandma’s bin cupboard and Nur, her granddaughter, is delighted. Grandpa thinks that it is just a mouse and keeps setting traps around the house to catch it. In the meanwhile, the little girl and her friends Ainara, Noelia, Unai and Peio enjoy themselves with Finn–that’s the leprechaun’s name–who has become the ally in their adventures.
