If The Loud House had a crossover again, I would suggest Hey Arnold, but this time, a Loud House Hey Arnold crossover would be paper animated instead of Flash because there were never times where a show migrates from Flash animation to paper animation.

And you know, Hey Arnold has always used paper animation, so I guess a chance of animation style changes would fit for both Hey Arnold and The Loud House because The Loud House was never made with paper animation before like SpongeBob, Looney Tunes, Ren & Stimpy, Camp Lazlo, Rocko, The Simpsons, Tom & Jerry, Mickey Mouse, Regular Show, Adventure Time, Ed, Edd n Eddy, and plenty more shows that used paper animation in their whole run.
