Achievement Walkthrough:

Very easy achievement
look for the Koala in the first area (its hugging a building) and kill it while moving so it doesn't instantly kill you

I recommend using the mech and side stepping.

After completing the game once, select "Final Boss" on the main menu then "Done" to restart at the beginning of the game. You should notice a dragon in front of you. Ride it and fly to the big white building in the middle of this area. You should notice a Koala holding onto it. Use your fire breath to quickly defeat the Koala.

I died a few times on this one and then did it first time in the mech by standing underneath him. Few hits and he fell on top of me and achievement unlocked.
