Around here we’ve known about the cloaking device for some time as hogs can move from one side of a garden to the other without being seen. They can also materialise inside a feeding station without having been seen going in. They have also developed a warp drive since they have been known to do a complete lap of my house at 1.2 times the speed of light.
During the Beast from the East one morning all the hog food had gone without leaving any footprints in the snow so either they have perfected tunneling or have developed a transporter beam.
I hope this helps.
