The niffler clasped the next coin in her front feet, sniffing it excitedly before putting it in her pouch. So many shinies readily available. It might be unfortunate for someone else to lose so many shinies, but for this niffler it was definitely her lucky day!

But then the niffler's ear quirked to attention, and she sat up to see human child boy approaching. She didn't pay him all that much attention, until he bent down and STOLE one of HER shinies. Her precious, precious shinies.

So, of course, she followed it. Jumping up right there and pushing her snout into the middle of the human boy child's warm fabric nest. HER shinies. Hmph.
