flying piranhas
 

the large piranhas in rivervale lake come out of the water and can follow you all through the zone if a guard doesnt kill it first. I am not sure if they do in other zones though

I want to say this was a classic bug that never got fixed on live? I recall that happening a lot in Nektulos in my noobie days, people even used them as pets, and the sharks attacking people on the boat in Ocean of Tears.

Certain mobs were land walkers. Certain mobs would memblur themselves if you jumped out of the water. Atleast that's how Classic works.

I believe all amphibious life in P99 has the ability to walk on land. This is a coding thing I believe.

A few examples from classic:

Corrupted Barracuda in LoIO would walk on land. Deepwater barracuda trash would not.
Sirens Grotto all the swordfish/seahorse would not walk on land (meaning you could jump onto land for safety)
Sharks would jump onto boats to eat you in OoT

Can confirm. I have killed all manner of fish in Loio out of water from both the pond & the lake.

There's a pending Haynar fix for new method of keeping amphibious creatures in the water.

alert

I thought it was weird when a shark didn't chase me on shore in Cobalt Scar.

Perhaps they are evolving into something new?
