A asteroid with life on it
(2) You manage to create a rock, but fail to create any semblance of life.
Destructinatdestroyers!
(2) Whoops. You accidentally create a bunch of pacifistic goldfish. They quickly die from lack of water.
Another jelly (jello) penguin this time alive.
(1) You're honestly starting to think that Toady rigged these dice. The glob of jello doesn't look like anything
at all, and it's a gibbering idiot. To add insult to injury, it smells like sweaty feet.
Make antimatter dwarves to dig into the sentient mountains.
(1) You're sure of it. The dice are rigged. You only manage to create smaller spheres of antimatter, and they quickly become friends with the sentient mountains.
A race of sentient explosions.
(4) Well, at least this worked. You've made a race of intelligent explosions, with about the force of regular TNT. Interestingly, they quickly form hostilities with the Mountain race. Possibly because of the mining uses of TNT.
Form a giant burrito planetoid
(4) You manage to create a gigantic burrito, about the size of Venus. The Mountains quickly form settlements on it, as do the Explosions. A violent land war soon erupts and both sides are taking major losses, however they fight on.
A very dark section of the Universe
A large ball of antimatter
A race of sentient mountains (At war with the Explosions. Has major settlements on the Great Burrito)
A race of sentient explosions (At war with the Mountains. Has major mining operations on the Great Burrito)
A large burrito, about the size of Venus. (Main Inhabitants - Explosions and Mountains)
Small antimatter spheres (Friends with Mountain; impartial to the war.)
This is fun to write!

Hope you are enjoying the Mountain-Explosion war!
And do you want to name the Mountains and Explosions, or just keep it at that?
