Elemental Wrath

Felix loves to solve problems with brute force. However, I believe there's something else behind the aggression of the local floral fauna.
You see, during the first days after our arrival the local animals and plants showed zero aggression.
It started a little later. Our mining routes were blocked by a herd of migrating mammals. We were compelled to use weapons.
Later on, it got so bad that we had to build a wall and secure it with cannons.
Day after day the animals and plants evolved, becoming more and more dangerous.
I need to study plants around our base. Bring me several mushroom samples. The symbiosis they form with other species is quite unique.

I could wait more, but you'd better hurry.

Alright, let's see what you got. Luckily, we can extract the life essence, or whatever they call it.
I can already see the change... They've grown some new prickles and hairs. I hope you were wearing gloves while gathering them. I wouldn't want you to lose your hands.
