N-Space Dog

A dog that exists in any N-Space, as opposed to a normal dog in 3-Space. Derived from the theorem that the shortest distance between two points is the straight line between them in any n space. A regular dog knows this in 3-space, so an N-Space dog knows this in N-Space.

I wrote all my notes on my N-Space Dog, do you think the professor will let me use it during the test?

rubbit

A rabbit, but said with an odd half-European accent so that it sounds like rubbit.

So there's a rubbit, and it wants to get across this river...
