Being a Zombie Tip:
Not sure if a thing is a brainz? Eat!

StrategyThis medal requires you to use the Foot Soldier.
Head to the park near the plant base in Sundrop Hills. You should see a statue there. Jump near it, and once you hit the maximum jump height, use the Rocket Jump ability to propel yourself to the top of the statue. Once you manage to stand on top of it, the medal should be awarded.
