See also https://github.com/azerothcore/azerothcore-wotlk/issues/6171 and https://github.com/azerothcore/azerothcore-wotlk/issues/6541 for what looks to be much the same problem with other aquatic creatures.

From my investigation, we are not transitioning from walk state to swim state properly. TC fixed this on their code but haven't checked any commits. The problem is very like how we use the Z axis to get a possible viable position. If we fix the Z axis we also might fix the bug where if mages blink submerged they getting sent to the bottom of the water body.

This NPC doesn't even patrol or do a ground/water transition

His spawn point is bugged and is clipped inside the rock

He has a random wander radius around that spawn point

[T1ti]

After slightly moving his spawn point away from inside the cliff, he seems to wander properly now

9272 probably fixes this
