Sky Spikes

The Sky Spikes is an artificial ice spikes biome for the purpose of arctic foxes, though to get the first 2 foxes, 2 tamed arctic foxes that did not like each other, AT ALL had 2 foxes which were then given to FireKnight2018 for transport to the Sky Spikes, the thing is incest was not a thought of idea for the Sky Spikes the only idea was just the arctic foxes, so the first 2 arctic foxes (promptly named 1 and 2) had 2 more kids named 3 and 4, then 3 and 4 had 2 kids named 5 and 6, yes I know original names but look when I brought them up there I didn't care for names, I mean they 3/4 of them are incest babies.
