Entity navigation is often not very realistic.

For example:

• Bats fly (walk?) along the ground, when evidently they have wings.
• As found in the MC-183 PR (#503), Guardians and rabbits were initially found to slide along the ground instead of walking properly with their legs.
• Ghasts have no idea how to navigate properly whatsoever.

Perhaps this should be worked towards in the EchoPet v3 AI, since the v2 AI is messy and not modular and/or easily editable.
