After thinking a bit about how awesome a creature that could survive absolute zero would be and how you would like to find such a creature, you decide to experiment a bit with biological rockets.
RESULTS:
1. Bird dies when it reaches a point in the atmosphere where there is not enough oxygen to breathe. You make a note of how high up this is.
2. You experiment with seed pods being shot up into space, as high as you can go. With a few modifications, you reach a 100% survival rate, and show some random animals the joys of orbital bombardment.
You modify WOLFTOPUS, adding some armour plating and strengthening its tentacles, to snap trees in twain. It will need it, seeing as the Primpsks are attacking the spawning pool.
With their tentacles, the WOLFTOPUSES manage to kill all of the fire-spiting bugs before they can, you know, spit fire. Of course, their resulting deaths caused their insides to spew everywhere, covering everything in flame, starting a forest fire and destroying the spawning pool. At least all the Primpsks are dead as well.
In related news, you've managed to (passively) infect around 2% of the Primpsk population in that city underground through their parasites. You are sure it'll go much faster as the amount of infected Primpsks increases.
