Watch seasons 1 through 5, then the first two episodes of season 6 before Operation: Z.E.R.O. Finish the season, take the Billy and Mandy crossover as a bonus, and close with Operation: I.N.T.E.R.V.I.E.W.S.
Good to know
Galactic Kids Next Door was a 2015 animatic pitch by creator Tom Warburton, never a produced episode, and Cartoon Network passed on it, so it is not listed. The crossover aired in 2007 inside the Billy and Mandy block.
