House Cat Rengar Skin:
Passive: Unseen Predator
Rengar leaps pounces (Much like some cats, all arms and legs spread out completely) at the target champion, who now has a red dot on their forehead
Q: Savagery
Rengar gets up on his hind legs and starts flailing madly at a mouse toy the target champion is holding before falling on his back and jumping up very quickly and acts as if he never fell
W: Battle Roar
Rengar gives a pathetic (Yet adorable) mew
E: Bola Strike
Rengar tries to play with one of those cat toys that are like a stick with something dangling on the end of it (You know what I mean) but it ends up speeding across the floor (As if it were hardwood) and raps around the enemy's legs
R: Thrill of the Hunt
Rengar vanishes from enemy sight, but for you and your allies (And enemies with true sight) you dashed under a rug and are chasing after something (There doesn't seem to be anything there, but Rengar sure seems to think there is) as you move
Recall:
Laser pointer dots. Leaser pointer dots EVERYWHERE!!!
