Playmobil 70800 Adventures of Ajuma Magical Energy Source Playset: The Magical Energy Source supplies the fairy world with energy. It is guarded by two Crystal Fairies. The main crystal lights up with the push of a button and a flickering light illuminates the lake. If the water wheel is turned, the plants start to grow, and wafts of mist rise up. Behind the cliff are secret pathways that allow the crystal thieves to slip past the watchful guards unnoticed. The weeping willow and several plants glow in the dark and create an enchanting atmosphere in a child's bedroom at night.
