Continuing with the suprise party skins... RIOT PLS
There is suprise party fiddlesticks and amumu, but I think there should be suprise party
because he hasnt gotten a skin in a long time and I think the animations and particles would suit him very well. I also think that suprise party
and
would be good because they both go invisible and would have a "suprise" kinda thing as fiddle does when he ults. any other ideas for suprise party?
suprise party 
VISUALS- wearing a party hat and costume like fiddle
Q- confetti explosion
w- line of silly string? Idk
e- he would have an AoE in suprise party colors, similar to fiddle ult
r- karthus does his usual channeling, and then when it hits, a party horn sound effect plays and confetti explosions around, that sorta thing.
suprise party
VISUALS- he would kinda like wear a party hat and costume like fiddle
PASSIVE- party horn sound plays when he jumps? Would be kinda annoying but it would be pretty cool.
Q- not much explaining needed here, just different visuals and particles, etc
w- just different colors and mabye a party horn sound effect? Damn, there are a lot of party horns in these skins
e- throws a silly string or a party horn?
r- Same idea as passive
suprise party 
Visuals- same as others
passive- you get the idea, different colors, etc
q- same as rengars kinda
w- he throws some silly string or party horns
e- not much explaining needed, just different colors and particles
r- khazix would go into stealth and reappear and do a party horn sound affect, kinda like rengars
PLEASE UPVOTE SO RITO CAN SEE

!
He already says surprise when he leaves stealth and his arrows can be streamers
