4th dimensional creatures and how to handle them

In the treatment for a 4th dimensional creature, several precautions must be made. Do make sure that the square prism space that you hold your creature in has 8 sides, all perpendicular to each other. Ah, and make sure those sides have sides too. Can never be too careful.

Now, if you wish to take your creature for a walk, do be VERY careful. If you're pulled even slightly in any direction with 4th dimensional values, that's an arm you're not getting back. Well, you didn't lose it, but... Yeah, it's gone. Do be sure to practice discipline with your pet, and ensure that the 4th dimensional ball is fully within your dimension before you pick it up to throw it. It will be unreasonably heavy, having its values^4 mass, but don't worry, it's also a good workout!

Now, of course, in the event that such a creature were to attack you, make sure you can generate either a black hole's worth of mass or exude enough exotic matter and negative energy to generate a wormhole. This should pin it in place long enough for you to call animal control to properly deal with the problem.
