Moving my otter up a slope

I’m trying to get my otter to move it’s location but it’s not moving because the terrain has a slope.

This is my code, it’s fairly simple. I plan to create random points in the terrain and get my otter to move randomly, thus, hardcoding the specific position will not help.

local otterModel = script.Parent

local myHuman = script.Parent:WaitForChild("Humanoid")
wait(10)
myHuman:MoveTo(Vector3.new(-21.705, -110.127, -48.7))

Using pathfindingservice insteads of humanoid:MoveTo is highly recommended as when there is an obstacle it will jump over it, and with pathfindingservice it will find its way to you.
