"Not a trick. Just magic," Phoenix said with a small smirk on his face. "Theres a lot more in here," he added and dug up several handfuls of somewhat shiny coins, a well polished silver tea spoon, shreds of tin foil paper, and other shiny stuff. Finally Gibson had enough and threw himself on the pile of his treasures and partly on the jewelery box, making distressed chattering sounds and looking suspiciously at the stranger and Phoenix in turn.
"It's okay, boy, no one's taking them away," Phoenix spoke to it calmly, slightly scratching the top of its head and then turned his attention to the other boy again, now with all serious expression again.
"This pouch is natural state to a niffler, but we can do the same to any bag or a pocket or any space really, like a tent or a room. Well, not you or I yet but teenagers and grown-ups can. See, we are wizards." he finally revealed and paused to let this sink in and see how the boy would take it.
