Human Technology
Living in the veil between worlds, certain technologies simply don't work. Signals for televisions, cell phones, etc, cannot be picked up in this strange and magical realm, and instead only appear as static and fuzz. Though other technology, such as ovens and stovetops, fascinate the creatures. The majority of strudels are vastly uninterested in human technology, but certain groups of strudels dedicate their time to researching and adapting human technology to the strudel world. While the temptation of getting up close and personal with some of these devices is temptings, strudels will only take things they know humans will not miss. A sugar cube here and there, a forgotten sock, etc. Highly valuable items such as phones and computers are simply too risky to take. (Not to mention, much too big!)
