This is Cloudy Bits, a pegasus specialized in developing advanced cloud storage technology.
Most of her research is about making clouds more durable and able to carry more weight, but she dreams about creating easily accessible cloud-based storage solutions for non-pegasi. Earth ponies in particular, with their lack of both natural and magical cloud shaping, barely can use most current cloud storage systems.
One of her latest innovations is the “Dropping Box”. Retrieving items from a cloud already works pretty well, but she still can’t figure out a way for earth ponies to get items and the box actually (back) into the cloud…
Nah, don’t worry. That cloud should easily be able to carry at least two anvils. In theory. Maybe. Hmm. She’d better test that…
