Fire Hazard
If you happen to burn up in this fire, you'll be trying the level again.
Keen 6: These yellow fellows have big teeth but their bite isn't the problem! Watch out where you shoot when these guys are around. They can reflect Keen's shots with their teeth, which can do some temporary damage.
Keen GBC: The Flect is always in a hurry, and has nowhere to go. This terminally worried creature has tentacles for hair and a reflective plate on its chest. It's best to be sneaky when dealing with a flect.
Found in: Keen 6, Keen GBC
Fleex Creature
The Fleex are amongst the finest engineers in the universe, having designed all the buildings and devices on Fribbulus Xax. Unfortunately, the Bloogs built them, devastating the sleek and elegant designs. The Fleex have very sensitive eyes (a natural consequence of spending a lifetime in a basement lab), so sensitive that they have to wear dark shades when they're out in the light (making them nearly blind). To compensate, they've developed an oversized ear which allows them to hear other creatures as they move around.
Temporarily stop most enemies by throwing flower powers at them and turning them into panting flowers.
Found in: Keen Dreams
Foob Creature
These are cute, harmless little yellow aliens. In fact, they're scared and will run away from you! By simply touching them, they will explode doing no damage to you. Or if you're really mean you could just zap them with your raygun.
Found in: Keen 3
