The bug

Players in creative mode frighten armadillos and it causes them to roll up into a ball. This is inconsistent with other mobs which are scared of players. Stray cats, ocelots, and rabbits are scared of players normally, but ignore players in creative mode.

Steps to reproduce:

1. Spawn Armadillos
2. Sprint near them in creative mode (even sprint flying scares them)
3. Observe they are frightened by the player

Expected result

They would not be frightened by players in creative mode

Observed result

They are frightened by players in creative mode
