EVENT THREAD #19: ITCHY & SCRATCHY LAND: Q & A AND STRATEGY THREAD: ACT III

I've completed the Quimby task and on part 4 of ms mouse's quest and her 8hr task is still there. Jeremy, Diane and I think itchy also have 8hr tasks for 120 knives but I don't fancy completing their quests just in case they disappear... I've also noticed that tapping on park visitors is only paying out 5 knives per visitor. This is only my 4th main event but if my memory serves me right, in the last 3 it was 10 per tap but slower spawn rate. Possibly swings and roundabouts? Maybe a more experienced player than me could shed more light :)
