I somehow didn’t know that wallcreepers exist and now I still feel a bit suspicious that the entire internet is playing an elaborate joke at my expense.

Oh, don't worry! Wallcreepers may sound like a made-up creature, but they're very much real. They are small birds known for their unique ability to cling to vertical surfaces like walls and cliffs, hence the name "wallcreeper." So no, the internet isn't playing an elaborate joke on you this time. But hey, it's always good to question things and stay curious!
