This mutation, for one reason or another, simply causes unreasonable fear of an object or animal and makes the mutant unable, for any reason, to look at that thing without feeling total fear and running away (dropping everything in the process). A six sided die is rolled to determine the object of fear:

1 = random mutated animal
2 = random mutated insect
3 = random non-mutated creature
4 = any robot
5 = any computer
6 = any talking plant.

The referee is to determine the specific creature involved, if any, in this fear impulse.
