New Jungle champion Idea

So thinking about how the jungle is laid out, I think there needs to be a champion with correlation with the map. Maybe a fighter that gains increased health regeneration after being in the river for a set amount of time. Or adding features like that can be buffed by certain creatures in the jungle, giving another reason to clear all the jungle to gain the maximum power of the champion. The abilities could play out as follows:

P- This champion has no mana, instead it uses water that it can gain from being in the river or standing in a puddle or recall. When in the river this champion gains the following:

• +20% increased speed
• +20% increased attack speed Also when you have both red and blue buff by either stealing or killing it, you gain the following:
• +20 attack damage
• +10% cooldown reduction
• +10 magic resist and armor
• Boosts the damage dealt in the ultimate by 30%

Q- champion throws a stone to a location dealing no damage and invisible to the enemy team. After 4 seconds the champion can be pulled to the darts location, and is granted 3 stones to throw as skill shots dealing moderate dmg. If all 3 stones hit the same target, you gain true sight of them and they bleed over 3 seconds for 100% attack damage. (dart would have larger range as it is leveled up)

W- Passive- Gains invisibility when standing on a puddle.

Active- Champion cuts the ground and forms a puddle that activates when an enemy champion walks over it. True sight is gained on that champion for 4 seconds and the range of the Q near puddles in increased. Total of 4 puddles on the map at a time.

E- champion has 3 dashes dealing damage, and if all landed on the same champion, the ground wraps them up stunning them and dealing crucial damage.

R-

Passive- There is a sea serpent in the river. Only this champion can see it until this ability is activated. This champion has the option to remove red and blue buff to add strength to the serpent.

Active- The serpent rises from the river and can be ridden on by this champion after channeling for 3 seconds. All abilities become Water Pulverizer, shooting water at the enemies and also having increased basic attack damage.

Ultimate is not very set in stone, but It would almost be like a mega gnar
