Or crazy idea do what "24" is doing and re-boot the whole show and pretend that this never happen

Stupid question how do you link the "Hey Arnold " world to Ren and Stimpy . One is a show that talk about life in a big city ( talks about drug abuse chocolate boy and poverty Lila ) And the other one is a dark tribute to 1950s American Animation . This sounds like a poor mans Super Smash bros
