If you are still curious, it’s dangerous to live there. (Well, at least for the average Waddle Dee.) Many plants there are poisonous, the mountains are large and steep and it’s hard to breathe when you’re on the peaks. And with the only two types of residents being thieves and living bombs, it’s a free for all there. Heh, you could say, every TAC for themself.
However, because the planet is so small, it’s well hidden and rarely has alien invaders, like those Dark Matter beings I have heard about.
